Objective To evaluate the recent effects of concurrent versus sequential chemo-radio-therapy in treatment for locally advanced non-small-cell lung cancer (NSCLC). Methods The clinical data of 39 patients with locally advanced NSCLC were analyzed retrospectively. The sequential therapy was 23 (sequential group) ,and the concurrent therapy (concurrent group)was 16. The total radiation dose was 60 ～ 65 Gy by conventional fractionation radiotherapy. In sequential group,the patients received induction chemotherapy for two cycles followed by conventional radiation therapy. In concurrent group,the patients re-ceived radiation therapy,at the same time the docetaxe was given every week. Results The recent efficien-cy(62.5%) of concurrent therapy was higher than that(43.5% )of sequential therapy. The clinical remission rate of the two groups was similar. Conclusion Concurrent chemo-radiotherapy in locally advanced NSCLC can increase the recent effect. The concurrent treatment method of docetaxel + three-dimensional conformal radiotherapy is advocated.

Objective To reproduce and validate the hexokinase reference method for glucose detection and compare other 5 routine glucose kits with this reference method. Methods The CDC hexokinase reference method for glucose detection was established and the performance was validated through testing a standard reference material (SRM) and participating in the IFCC ring-trial for reference laboratories for glucose evaluation. The CLSI EP 9-A2 protocol was used to compare the 5 routine glucose kits with the hexokinase reference method. Forty serum samples were analyzed by 5 routine kits and the hexokinase reference method. Results When SRM 965a was determined by the reference method,the bias of level 2 and level 3 were 0. 93%, -0. 23% respectively. The results for IFCC ring trial were within the accepted range. For the 5 routine kits, the confidence intervals of the predictive bias at the medical decision point Xc (Xc = 6. 11 mmol/L) were all within the range of defined acceptable error (10%) and the range of biological variation bias (6.9%). Conclusions The hexokinase reference method for serum glucose was reproduced in our lab. The serum glucose results measured with 5 routine kits were different from results detected with the reference method, but the bias was acceptable,and it will not affect the detection results.

The article discussed the objectives, significance and contents, as well as approaches in the education of clinical pathways. It recommended a tiered education for hospital leaders, medical care workers, office staff, patients and their family members, and different target groups and contents in the education for clinical pathways application.

Objective To investigate the relationship between infection of helicobaeter pylori(Hp) and iron deficiency anemia(IDA) and to explore effective clinical treatments for patients with Hp associated IDA . Method 1. The Hp infection ratio of 40 chronic gastritis with IDA and 42 patients without IDA were counted up respectively. 2. 36 patients with Hp-positive chronic gastritis were divided into two groups randomly. One group was treated by using Hp eradication therapy in conjunction with oral iron supplement and the other using iron supplement only. The hema-tological parameters before and after treatment are measured and the effectiveness of the treatment was evaluated. Re-sult The Hp infection ratio in chronic gastritis patients with IDA is |figher than that in patients without IDA and the difference is significant. After Hp eradication therapy in conjunction with iron supplement Hb. serum iron and serum ferritin level in Hp associated IDA patients are increased significantly while that for patients treated by using iron sup-plement only have no significant improvement. Conclusion It appears that Hp infection may be related to IDA. When iron supplement treatment has no obvious effect to an IDA patient,lt may suggest a ease of Hp associated IDA. The i-ton supplement treatment has positive effects to IDA patients after Hp eradication.

Objective To observe the effects of tuina on muscle atrophy after denervation and on muscle satellite cell proliferation.Methods Ninety male rabbits with denervated skeletal muscles were randomly divided into a normal group,a control group,and a treatment group.Tuina was applied daily to the right gastrocnemius muscles beginning one day after the modeling.Changes in muscle wet weight ratio and the amount of skeletal muscle satellite cells (SCs) were observed 1,2 and 3 weeks and 1,2,4 and 6 months post-modeling.Results The muscle wet weight ratios of both the treatment group and the control group were lower than those of the normal group.The weight ratio in the treatment group was significantly different from that in the control group after 2 months (0.578 ±0.163 vs 0.470 ±0.062),4 months (0.575 ±0.110 vs 0.453 ±0.101) and 6 months (0.559 ±0.083 vs 0.446 ±0.048).The amount of SCs was also significantly different in the treatment and control groups after 1 week (16.83 ±5.31 vs8.67±2.58),2 weeks (51.83±7.94 vs32.00±6.93) and4 months (11.17±3.49 vs 17.67±4.18).Conclusion Tuina therapy can promote proliferation of satellite cells and delay the atrophy of denervated skeletal muscles.

Background and purpose:The gastric cancer is the highest incidence of malignant tumors in the world. The main treatment methods for gastric cancer are operation and chemotherapy. But the effect is not good. With the rapid development of economy and molecular biology, early diagnosis and molecular targeted therapy for gastric cancer has become a research hotspot. The oncogene overexpression and the anti-oncogene lower expression are closely related with gastric cancer.CDC4/FBXW7 is an anti-oncogene, butc-Myc is an oncogene. The previous research showed that CDC4 affected the expression of many oncogenes, such as Cyclin E. This study aimed to investigate the expression of CDC4 and c-Myc in gastric cancer and to elucidate the potential relationship between their expressions and clinical pathological characteristics.Methods:Semi-quantitative reverse transcription polymerase chain reaction (sRT-PCR), immunohistochemistry and Western blot method were used to determine the mRNA and protein expressions of CDC4 and c-Myc in 40 specimens of gastric carcinoma tissues, corresponding adjacent tissues and normal mucosal tissues. The expressions of CDC4 and c-Myc and the clinical pathological characteristics were analyzed.Results:The protein expressions of CDC4 in gastric cancer tissues were signiifcantly lower than those in adjacent tissues and normal mucosal tissues (P<0.05), whereas the protein expression of c-Myc in gastric cancer tissues was signiifcantly higher than that in adjacent tissues and normal mucosal tissues (P<0.05). The protein and mRNA expression of CDC4 and c-Myc were correlated with differentiation, TNM stage, lymph node metastasis, inifltration, but not with patients’ gender, age and site of cancer (P<0.05). There was a signiifcant negative correlation between CDC4 and c-Myc at the mRNA and protein expression levels (P<0.05).Conclusion:The lower expression of CDC4 is correlated with differentiation, TNM stage, lymph node metastasis and inifltration. c-Myc overexpression is likely to be the CDC4 loss. It suggests that the loss of CDC4 may be a valuable marker for assessing the diagnosis and treatment and the prognosis of gastric cancer.

Purpose To investigate the clinical effect of ultrasound guided drainage combined with different hardeners for simple breast cysts,and to further provide reference for individual treatment.Materials and Methods Clinical data of 117 cases breast simple cysts were analyzed retrospectively,of which 42 cases were routine ultrasound-guided puncture combined with fluid injection of hypertonic sugar (group A),40 cases were routine ultrasound guided drainage combined with ethanol injection therapy (group B),and 35 cases were routine ultrasound guided therapy alone (control group).The clinical efficacy and adverse reactions were compared among the three groups after treatment.Results The total effective rate of group A was 95.24％,group B was 97.50％,and control group was 82.86％.Total effective rate of group A and B had no significant difference (P＞0.05),which were both higher than control group (P＜0.05).The adverse reactions rate of group B was higher than group A and control group,which had statistical significance (P＜0.05).Conclusion Ultrasound guided injection of hypertonic sugar or ethanol after drainage treatment for simple breast cysts can both obtain satisfactory clinical results,but adverse reactions of the former one are mild,it should be widely applied.
