OBJECTIVE:To investigate the effect of thymosin α1 combined with chemotherapy on immune function in patients with advanced gastric cancer and quality of life. METHODS:90 patients with advanced gastric cancer were randomly divided into observation group and control group with 45 cases in each group. Control group was treated with FOLFOX4 chemotherapy plan(so-dium oxaliplatin+calcium folinate+fluorouracil),and observation group was additionally treated with thymosin α1 1.5 mg subcutane-ously,once a day,on the basis of control group. A treatment course lasted for 3 weeks,and both received 3 courses of treatment. The immune function and quality of life were evaluated in 2 groups. RESULTS:The effective rate of observation group was 57.8%,and that of control group was 53.3%;there was no significant difference between 2 groups (P>0.05). The incidence of leukopenia in observation group was 24.4%,which was significantly lower than control group (55.6%),with statistical signifi-cance(P<0.05). There was no statistical significance in CD4+,CD8+ and NK score between 2 groups before chemotherapy(P>0.05). After treatment,above index of observation were all higher than those of control group,with statistical significance (P<0.05). The total health QLQ-C30 EORTC score in observation group was higher than in control group after chemotherapy,with sta-tistical significance(P<0.05). CONCLUSIONS:Thymosin α1 combined with chemotherapy can significantly improve the immune function and quality of life.

OBJECTIVETo establish a RP-HPLC-PDA method for determination of five triterpenic acids (pomolic acid, hawthorn acid, corosolic acid, oleanolic acid and ursolic acid) in different parts of Salvia chinensis.

METHODThe isocratic elution and separation was achieved on a Kromasil C18 column (4.6 mm x 250 mm, 5 microm), using acetonitrile-water (90:10) as the mobile phase at a flow rate of 0.8 mL x min(-1). The detection wavelength and column temperature were set at 205 nm and 28 degrees C, respectively.

RESULTThe calibration curves of pomolic acid, hawthorn acid, corosolic acid, oleanolic acid and ursolic acid were linear over the ranges of 0.096 0-2.400, 0.1230-3.075, 0.2420-6.050, 0.2830-7.075 and 0.2730-6.825 microg (r = 0.9998, 0.9997, 0.9999, 0.9995, 0.9999), respectively. The average recoveries were 98.43%, 98.13%, 100.6%, 98.19% and 99.15%%, respectively, with RSD (n=6) being 1.3%, 0.67%, 1.2%, 0.87% and 0.43%.

CONCLUSIONThe proposed method is so simple and highly reproducible that it promises to be applicable for determination of major triterpenic acids in S. chinensis.

[Objective]To analyze the causes of anterior knee pain after intramedullary(IM) nailing treatment of tibial shaft fractures.[Method]A total of 256 patients with tibial shaft fractures were treated with intramedullary nailing from 2000 to 2007 in our hospital.There were 183 males and 73 females with a mean age of 45 years.All patients were followed up at least once after fracture healing.[Result]Among 256 patients,166 experienced anterior knee pain,accounting for 65%.Ninety-six(58%) treated with transtendinous nailing complained of and 70(42%) treated with paratendinous nailing complained of anterior knee pain.It was worsened after activity but relieved only in 33(20%) by resting or taking analgesic drugs.The anterior knee pain disappeared one year after the IM nailing was taken out.[Conclusion]Anterior knee pain can not be reduced by different approaches of operation for tibial shaft fractures.However,the removal of intramedullary nailing and the muscle exercises around the knee joint can reduce the occurrence of anterior knee pain.

With the progress of human civilization,the harmonious development of society is gradually realized by different researchers.Medicine,as a science directly serving humans,emphasizes more on humanism than other sciences.Medical research is not only characterized by scientificity and innovativeness,but also by ethicality.More and more biomedical journals are paying attention to issues of ethics.This review discussed the ethical issues in academic medical writing based on the Uniform Requirements for Manuscripts Submitted to Biomedical Journals published by International Committee of Medical Journal Editors (ICMJE) and the discussions by Committee on Publication Ethics (COPE).

目的探讨急性心肌梗死(AMI)患者实施早期康复护理的效果。方法对86例AMI患者根据住院日期分为对照组和实验组,分别采用传统护理方式和早期康复护理方案实施护理,并进行效果比较。结果两组在心功能、心绞痛、心理状态、并发症、平均步行距离、住院时间等方面均有显著性差异(P<0.05或P<0.01)。结论实施早期康复护理效果优于传统护理方法。

Objective To evaluate the diagnostic value of color Doppler ultrasonography(CDUS)and molybdenum mammography for breast tumor.Methods 86 breast diseases which were diagnosed by the surgery and pathology,were prospectively analysed,40 in mammary carcinoma,and 46 in mammary benign disease.All the patients were examined with CDUS,CDFI and molybdenum mammography.Diagnosis was made in every case compared using two methods(CDUS and molybdenum mammagraphy)with any using only one method.Results There is significant difference between mammary carcinoma and mammary benign disease in CDUS.The mammary carcinoma patients'blood stream signal is abundant. The diagnostic veracity of using both CDUS and molybdenum mammography for breast tumor is obvious higher than that of the any only one method.Conclusion Combined CDUS with molybdenum mammography which is the optimal methods of the mammary image examination,can improve the diagnostic veracity of breast tumor.

Objective To analyze the imaging performances and significance of Modic changes on X-ray,CT and MRI.Methods The imaging data (MR,CT and X-ray)of patients with low back pain were retrospectively analyzed.The selected patients’images were studied on the same work station by the two physician experts in muscle and bone imaging.A double-blind method was used. Firstly,MRI was used to sort the MC.Then,the alterations of the density in the lesions on X-ray plain film and CT image were measured.if the judgments of the two readers were inconsistent,another professor of radiology will join the discussion and consist-ent results will be got finally.The data were recorded using Excel 2010,and processed for statistical analysis using SPSS 1 6.0.Re-sults A total of 47 cases that met the requirements were collected which included 1 6 males and 31 females,aged from 32 to 76 years,with a median age of 56.0 years.A total of 93 on MRI endplate were changed.However,a part of lumbar endplates with MC on MRI images were displayed as higher density than normal vertebral body on the X-ray and CT reconstruction images (total of 36).The occurrence rates of Type Ⅰ,Type Ⅱ,Type Ⅰ/Ⅱ were 40.0%,14.8%,58.3%,respectively.But the occurrence rate of Type Ⅲ (100%)and hybrid Type which contained type Ⅲ were 100%.Conclusion Some Modic typeⅠ,Ⅱ,Ⅰ/Ⅱchanges in X-ray plain film, CT reconstruction images had a higher density,speculating that there is reactive new bone formation,which reflects the internal ver-tebral body bone mineralized rather than the change of the bone marrow.

AIM　The purpose is to examine the chemical constituents in the fruits of Terminalia chebula. METHODS　Using combined chromatographies over silica gel, Diaion HP-20, Toyopearl HW-40 and MCI gel CHP -20P to purify the constituents of Terminalia chebula, and identifying their structures on the basis of spectroscopic and chemical evidence were purified. RESULTS　Twenty one hydrolyzable tannins and related polyphenols were characterized, here reports eight of them: 2,3-(S)-HHDP-D-glucose, 3,6-di-O-galloyl-D-glucose, 6-O-galloyl-D-glucose, (-)-shikimide 4-O-gallate, (-)-shikimic acid 3-O-gallate+(-)-shikimic acid 5-O-gallate, methyl gallate and 1,2,6-tri-O-galloyl-β-D-glucose were reported.
