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.

The paper analyzed the compensation mechanism applied in public hospitals in different localities in China,which are currently experimenting with the zero price margin for drugs.It also introduced the revenue variations resulting from this practice.It is discovered that public hospitals can hardly make their ends meet with merely governmental financial input,and that lowered income of doctors and price distortion arc evident in those experimental hospitals,with little progress in overcoming the subsidization of medical services with drug sales.The authors recommended a comprehensive reform,the mechanism of diversified health input,change of internal incentive mechanism within the hospital,improvement in the healthcare service pricing mechanism,and exploration of new operation mechanisms for public hospitals.

BACKGROUND: Alienation is derived from dissimilation in philosophy.It is practically defined as the subjective state of individuals who develop negative feelings such as social isolation, uncontrollable and meaningless sense, oppression, and self-alienation because they are alien to others, the.society, nature and themselves, and even feel controlled.OBJECTIVE: To investigate alienation from psychological perspective,aiming to construct and verify the theoretical hypothesis of alienation,thereby working out alienation scale for adolescent students.DESIGN: Cross-sectional investigation.SETTING:National Key Research Center of Basic Psychology and National Key Liberal Arts of Southwest Normal University.PARTICIPANTS: The investigation was carried out from March to June 2000. The method of cohort stratified random sampling was adopted and the questionnaire was administered to adolescent students in Chongqing City and Lanzhou City. Inclusion criteria: volunteer students of grade one in junior high school to grade four in colleges. Exclusion criteria: Those who had incomplete data or had differences of more than 6 points in the total scores for three matched lie-testing questions in the questionnaire. A total of 1502 pieces of questionnaire were collected (including 1 066 questionnaires used for exploratory factor analysis and 436 questionnaires for verifying factor analysis); the age of the students covered the whole range of adolescence, and the boy-to-girl ratio in each grade was matched.METHODS:We combined literature analysis, investigation research and interview. The details are as follows: First, theoretical hypothesis was put forward based on literature analysis; then related variances were collected through interviews and open questionnaires, which were compared with the items in scales used home and abroad at present so as to work out predicting questions for adolescence alienation questionnaire. Finally, 52 items were screened out and used to construct the preliminary questionnaire. The formal alienation scale was made after standardized designation of behavioral variances, and verified for alienation analysis in adolescent students.MAIN OUTCOME MEASURES: Behavioral apparent variances were collected based on interviews and open questionnaires, and used as psychological potential variances after statistical processing.RESULTS:Data of 1502 pieces of questionnaire were analyzed.① The correlation coefficient of each item in the scale was over 0.35. ② The correlation coefficient of each item with the dimension was over 0.30, with statistical significance(P ＜ 0.01). ③ The reliability coefficient of each item was over 0.39 with great significance(P ＜ 0.01). ④ Alienation was displayed in three dimensions: social alienation, interpersonal alienation and surrounding alienation, which were associated with the correspondingdimensions of related scales (P ＜ 0.05-0.01). ⑤Alienation could be divided into 9 levels: sense of meaninglessness, sense of self alienation, isolation, nature alienation, parent alienation, environmental alienation, sense of uncontrollability and social alienation. Parameters that accorded with the theoretical hypothesis and used for verifying analysis were proved rational.Based on the analysis of the 9 first-rank factors, second-rank structural model of 3 unrelated factors were obtained using main component analysis and the maximum variance cross rotation with the optimal coefficients of simulated parameters of: X2/df=4.87;GFI=0.94;A GFI=0.90;RMR=0.0S;NFI=0.93;NNFI=0.92;CFI=0.95;IFI=0.95.CONCLUSION: Alienation scale has been proved to be reliable and valid. It can be used to assess alienation in adolescent students and has potential value of application in healthy psychological development and psychological education.

Objective To study the image findings and clinical characteristics ofmultislice helical CT (MSCT) in intrahepatic mass-forming cholangiocarcinomas.Methods Fifteen patients of pathologically confirmed intrahepatic mass-forming cholangiocarcinomas were studied retrospectively.The image findings of MSCT and clinical manifestations,laboratory tests of each case were recorded respectively.Results All patients image findings of MSCT:density was uneven,moderately low congestion densities was 14 patients.High and low congestion densities was 1 patient,pathologically confirmed bleeding.Obscure boundary and atrophy of liver lobe was 10 patients,adjacent liver capsule retraction was 11 patients,combined with ductal dilatation was 11 patients,intrabepatic calculi was 5 patients,ductal wall thickening with or without narrowed bile duct was 9 patients,satellite nodules was 10 patients.Enhancement scanning showed:peripheral enhancement was 11 patients,arterial phase border enhancement was 11 patients,all had delayed enhancement,honeycomb-like enhancement was 3 patients,obliteration or invasion of portal vein was 11 patients.Conclusion There are some clinical characteristics of MSCT findings in intrahepatic mass-forming cholangiocarcinomas.

This study is to observe anti-lipotoxic effect of sesamin on renovascular hypertensive rats fed with a high-fat, high-sucrose diet. Thirty-four complex model rats were induced by two-kidney, one-clip method and on high-fat and refined-carbohydrate diet for thirteen weeks. From the fifth week, intragastric administration of sesamin (120, 60 and 30 mg x kg(-1) x d(-1)) lasted for eight weeks. Blood pressure (BP), blood fat (BF), blood glucose (BG), free fatty acids (FFA), insulin (Ins), tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 were determined. Pathological changes of pancreas, perirenal fat and liver were semiquantitatively analyzed. In sesamin (120 and 60 mg x kg(-1) x d(-1)) group, it was found that there were decrease of levels of BP, BF, BG, TNF-alpha, IL-6 and FFA, improvement of insulin resistance and glucose tolerance, alleviation of body weight, humid weight of fat, liver and pancreas and their organ index, and reduction of islet cell hyperplasia and amount of lipid droplet vacuoles in lipocyte and hepatocyte. It is implied that sesamin had anti-lipotoxic effect and its mechanism may be closely associated with the amelioration of insulin resistance via reducing lipidoses in hepatocyte and inflammatory adipokines such as TNF-alpha and IL-6.

Objective To study three single nucleotide polymorphisms (SNP), SNP-43, -19 and - 63 of calpain-10 (CAPN10) gene in pregnant women with glucose metabolism disorders and their relationship with the risk of these disorders. Methods Totally, 270 pregnant women including 156 with an abnormal oral glucose tolerance test (study group) and 114 healthy controls were selected among those delivered at the Department of Obstetrics and Gynecology, Peking University First Hospital from Jan. 2005 to Dec. 2006. The SNP of CAPN10 gene at posifons 43, 19, and 63 were analyzed by primer-introduced restriction analysis-polymerase chain reaction (PIRA-PCR). Results (1) The frequencies CAPN10 SNP-19 2R/2R genotype (26.9% ,42/156) and 2R allele (48.9%, 152/312 ) were higher than those in controls (12.3% ,14/114 and 36.8% ,84/228, respectively; P=0.012, 0.006). (2) Stratified analysis according to family history of diabetes mellitus showed the proportion of the CAPN10 SNP-19 2R/2R+2R/3R genotypes (83% ,47/57) in the study group were significantly higher than that of control group (52%,11/21 ; P=0.009), and the proportion of SNP-63 T/T + T/C genotypes(47% ,27/57) in study group were significantly higher than that of control group (14%, 3/21 ; P=0.026) among those with positive family history. (3) The combined effect of CAPN10 SNP-43, -19 and -63 on glucose metabolism disorders was analyzed by comparing with the other haplotypes and showed that the haplotype 121 distribution in study group was significantly higher than those in controls(P=0.036), and 221 haplotype was significantly lower than controls (P=0.042). Conclusions (1) CAPN10 SNP-19 is associated with glucose metabolism disorders in pregnant women. And 2R allele might be the risk factor. CAPN10 SNP-19 2R/2R +2R/3R and SNP-63 T/T + T/C genotypes might increase the risk of glucose metabolism disorders in women with positive family history. Haplotype 121 might increase the risk of glucose metabolism disorders in pregnant women and 221 be a protective factor.

Objective Probing into the rationale of DRGs payment standards for references to making DRGs payment standards.Methods Based on the DRGs grouping results of circulatory diseases cases admitted by a tertiary hospital from 2003 to 2005,two typical combinations were selected to determine the payment standard for each DRGs combination.Unnecessary medical expenses were excluded.Results According to the percentage of unnecessary medical expenses,Angina,non-special nursing,and class 1 nursing were in a group,with unnecessary medical expenses per ease of 758.00 yuan;CAG,single stent implantation,acute myocardial infaction as the main diagnose were in a group,with medical expenses per case of 2814.03 yuan;such expenses account for 6.20% of the total hospitalization expenses of both groups.Conclusions If the average expenses with unnecessary medical expenses excluded are set as the combined payment standard,hospitals will be restrained from unnecessary medical behaviors and expenses so incurred.
