[Objective]To explore the operation modes and outcomes of proximal femur tumor with pathological fracture. [Methods]There were 46 cases to be reviewed from october 2001 to June 2007,all were respectively treated by 6 surgery methods:curettage and bone grafts after fracture healing by external fixation in 7 cases (Group A),bone transplantation and internal fixation in 11 cases (Group B),fibula grafting with blood vessel after curettage in 6 cases (Group C),bone cement plugging and interlocking intramedullary nailing after curettage in 8 cases (Group D),tumor segment resection and endoprosthesis in 12 cases (Group E),and hip joints disarticulation in 2 cases (Group F).[Results]According to Enneking evaluation standard in limbs function,the excellent to good rate was 85.7% in Group A,88.8% in Group B with 9 cases followed up,83.3% in Group C,66.6% in Group D with 5 patients died,75% in Group E with 5 patients died and 1 case recurrence.[Conclusion]Proper operation methods of the proximal femur depend on the basis of tumor characteristics,the degree of damage and fracture displacement. Benign tumor could be treated by tumor curettage and bone grafts,femoral neck fracture by rigid fibula graft,malignant tumor by prosthesis replacement or interlocking intramedullary nails.

The learning theory of constructivism, formed by the development of cognitive psychology, shaped well thecognitive structure of medical students. It paid attention to the curriculum configuration and integration, and also thoughtmuch of the situated instruction. The theory embodied the main ideology of regarding medical students as the instruc-tional central and the principle of independent study. It offered the theoretical basis and a new view for the setting ofclinical integrate curriculum.

Objective To investigate the clinical effects of lactobacillus acidophilus combined with glutathione in the treatment of nonalcoholic fatty liver disease.Methods 120 patients with nonalcoholic fatty liver disease were selected,and they were randomly divided into control group (60 patients used glutathione alone) and observation group (60 patients received lactobacillus acidophilus on the basis of control group).The clinical efficacy,liver function index,blood lipid index and the ultrasonography grading of fatty liver before and after treatment of the two groups were compared.Results The clinical total effective rates of the control group and the observation group were 76.67％,91.67％,respectively.The total effective rate of the observation group was significantly higher than that of the control group(x2 =10.52,P ＜ 0.05).The levels of AST,ALT and GGT of the observation group after treatment were significantly lower than those of the control group and before treatment [(36.89 ± 7.14) U/L,(36.89 ± 7.14) U/L,(36.89 ±7.14) U/L vs.(49.36 ± 11.08) U/L,(45.91 ± 10.24) U/L,(90.28 ± 20.70) U/L;(36.89 ± 7.14) U/L,(36.89 ± 7.14) U/L,(36.89 ± 7.14) U/L vs.(92.90 ± 24.3) U/L,(81.11 ± 17.37) U/L,(147.27 ± 34.19) U/L,t =2.88,2.54,2.91;3.01,3.36;3.18,3.48;3.41,3.87;all P ＜0.05).The levels of TG,TC,HDL-C and LDL-C of the observation group after treatment were significantly better than those of the control group and before treatment [(1.66 ± 0.42) mmol/L,(4.05 ± 0.77) mmol/L,(1.69 ± 0.60) mmol/L,(2.44 ± 0.38) mmol/L vs.(2.13 ± 0.80) mmol/L,(4.64 ± 0.94) mmol/L,(1.45 ± 0.48) mmol/L,(2.97 ± 0.57) mmol/L;(1.66 ± 0.42) mmol/L,(4.05 ± 0.77) mmol/L,(1.69 ± 0.60) mmol/L,(2.44 ± 0.38) mmol/L vs.(2.71 ± 1.33) mmol/L,(5.42 ± 1.27) mmol/L,(1.08 ± 0.36) mmol/L,(3.49 ± 0.71) mmoL/L,t =2.43.2.13,2.55,2.07;3.02,3.41;3.11,3.65;2.81,3.30;2.87,3.15;all P ＜ 0.05).In the control group,normal in 6 cases,mild in 24 cases,moderate in 21 cases and severe in 9 cases as fatty liver degree;in the observation group,normal in 13 cases,mild in 30 cases,moderate in 13 cases and severe in 4 cases as fatty liver degree.The ultrasonography grading of fatty liver of the observation group after treatment were significantly better than those of control group and before treatment (U =3.74,5.20,all P ＜ 0.05).Conclusion Lactobacillus acidophilus combined with glutathione in the treatment of nonalcoholic fatty liver disease can efficiently promote the recovery process of liver function,regulate blood lipid levels and is helpful to improve the imaging grading.

Objective Toinvestigatethecorrelationofsmallvesseldisease(CSVD)causedacute lacunarinfarctionandurinemicroalbumin.Methods Theclinicaldataof136patientswithacutelacunar infarction admitted to the Department of Neurology,Shengjing Hospital of China Medical University from November 2012 to April 2014 were analyzed retrospectively. They were divided into either a CSVD group (n=72)or a cerebral large vessel disease (CLVD)group (n=64)according to their carotid artery color Doppler ultrasound and head magnetic resonance angiography findings. The levels of urinary microalbumin in both groups were observed and compared. SAS 9. 1 software was used to conduct statistic analysis. A Logistic regression analysis was used to determine the independent risk factors for CSVD caused acute lacunarinfarction.Results TheconcentrationofurinemicroalbuminoftheCSVDgroup(22±13mg/L) was significantly lower than (29 ± 14 mg/L)that of the CLVD group. There was significant difference (P<0.05). There was significant difference in the increased urine microalbumin levels between the CSVD group and the CLVD group (P<0. 01). There was an increasing trend for the proportion of patients with urine microalbumin concentration 10- <30 mg/L (56. 9%[41/72])in the CSVD group compared with the CLVD group (26. 6%[17/64]). Logistic regression analysis showed that the slightly increased microalbuminuria was associated with CSVD caused acute lacunar infarction (OR,3. 130,95%CI 1. 481-6.618;P<0.01).Conclusion Theslightlyincreasedmicroalbuminuriaisanindependentriskfactorfor CSVD caused acute lacunar infarction.

Objective To explore the chromosome features of pancreatic cancer cell lines from Chinese patients. Methods G-band Chromosome karyotyping was performed on pancreatic cancer cell lines of PC1, PC2, PC3, PC4 and PC7 that were established in our laboratory. The results of cytogenetic analysis were confirmed by fluorescence in situ hybridization using Chromosome 3, 13 18 and 20 paint probes. Results All the 5 cell lines were hypotriploid and showed a modal number of 58 for PC1, 56 for PC2, 61 for PC3, 53 for PC4 and 54 for PC7 with different proportion of complex chromosome rearrangements including dicentric chromosomes, double-minute chromosomes, ring chromosomes, acentric fragments or complex chromosome translocation, etc. Conclusion Hapotriploid accompanied with complex numerical and structural chromosomal rearrangements is the main cytogenetic marker of chromosomal instability in pancreatic cancer cell lines. Molecular cytogenetic techniques have to be used beside conventional G-band karyotyping for accurate identifying abnormal chromosomes of pancreatic cancer cell lines.

The prognosis of malignant tumors of the digestive system is still a matter of close attention in the medical and health field. At present, evaluating the prognosis of patients with digestive system malignant tumors is mainly based on the TNM staging of the tumor after surgery. As one of the ten characteristics of cancer, inflammatory indicators have certain guiding significance for the prognosis and treatment of patients with malignant tumors of the digestive system. As a new type of inflammation index, the systemic inflammatory response index is significantly better than other traditional inflammatory indexes in evaluating the prognosis of patients with digestive system malignant tumors. This article reviews the related studies on the systemic inflammatory response index in evaluating the prognosis of digestive system malignant tumors.
