OBJECTIVETo explore the therapeutic effects of internal fixation with Herbert screws for the treatment of Pipkin type I and type II femoral head fractures.

METHODSFrom January 2008 to December 2012, 23 patients with Pipkin type I and type II femoral head fractures were treated with open reduction and internal fixation by Herbert screws through Kocher-Langenbeck approach. Twenty-three patients (aged 18 to 52 years with a mean of 35.5 years, including 18 males and 5 females patients, 8 left hips and 15 right hips) with femoral head fractures and posterior hip dislocation. The fracture was classified according to Pipkin classification based on the radiographic findings, 5 patients had type I and 18 had type II fractures. The duration time from admission to the operation ranged from 6 to 72 h (averaged 32 h). The clinical and radiographic outcomes of the patients were measured using Thompson-Epstein scoring scale. The Harris hip score(HHS) was used to evaluate and compare hip functions at the latest follow-up between affected and healthy sides.

RESULTSAll the patients were followed up, and the duration ranged from 20 to 48 months (averaged 30 months). According to Thompson-Epstein system, 12 patients got an excellent result, 6 good, 4 fair and 1 poor. The average HHS at the finial follow-up was 87.80 ± 8.46 (ranged from 66 to 95), which is similar to that in the healthy side 90.10 ± 6.35 (ranged from 72 to 98) (t = 1.044, P = 0.302). The complications such as deep infection, and deep vein thrombosis were not found. At the 3rd year during follow-up,4 patients had avascular necrosis of femoral head. At the 1st year of follow-up, 1 patient had hip pain after walking,screws loosening and shift after trauma,and serious complications of traumatic arthritis. All the 5 patients were treated with total hip arthroplasties.

CONCLUSIONThe treatment of internal fixation with Herbert screws through the Kocher-Langenbeck approach is effective for Pipkin type I and type II femoral head fracture. The method is reliable and valuable for recommendation. However, such fracture may have avascular necrosis of femoral head and complication of traumatic arthritis, which should be observed carefully in clinic with preparation of the prevention and treatment measures.

Objective To analyze the alterations of serum protein in ESCC,compare alterations of serum protein with and without LM. Methods Serum samples were collected from 64 ESCC patients before operation and 60 cases with gender and age-matched healthy controls,special serum protein or peptide spectra was determined by SELDI-TOF-MS measurement after treating the sample onto weak cation exchange (WCX2) protein chip for each case. The serum protein profiles were compared by Biomarker Wizard Software between the ESCC patients and healthy controls, and among ESCC patients stratified according to gender, age, location of tumor, size of tumor, infiltration and with or without LM. Results (1)120 protein peaks were detected at the molecular range of 0 to 50000 in comparing of ESCC patients and healthy controls. 31 significantly different peaks were found between ESCC patients and healthy controls (P <0.05), 10 peaks were selected(P<0.01). (2) One significantly different protein peak (m/z 4174) was detected between T1 and T3, T4 (P<0.05). (3) There were three significantly different protein peaks (m/z 3970,4174 and 4277) between with LM and without LM (P<0.05).The peak (m/z 4174) was shared by two groups above. (4) No significant different protein was found when patients stratified according to gender, age, location of tumor and size of tumor. Conclusion Significant difference exists in serum proteins between ESCC patients and healthy controls. There are statistical difference exists in serum proteins between T1 and T3, T4, with LM and without LM. This difference is less than between ESCC patients and healthy controls. Some commonness is existed in serum protein fingerprint for patients with serious infiltration and with LM.

Objective To elucidate the effects of different modes of partial parenteral nutrition (PPN)on immunological function of T-lymphocyte in non small cell lung cancer(NSCLC)patients during chemotherapy.Methods Ninety-three patients with non-small cell lung cancer were randomly divided into three groups:the control group(30 patients),the low dose of PPN(32 patients) and the high dose of NNP(31 patients).Exactly the same chemotherapy was applied to each of three groups.During chemotherapy,three groups were supplied the same diet,the control group received conventional treatment;the low dose group and the high dose group received additional parenteral nutritional support besides diet.The low dose group was given 250 ml 9-AA daily and the high dose group was given 500 ml 9-AA daily.The T lymphocyte subsets CD3~+,CD3~++CD4~+ ,CD3~++CD8~+ and cells were detected respectively before and after chemotherapy.Results In all of the three groups,the percentage of NK cells,CD3~+ and CD3~++CD4~+ cells were decreased significantly before and after chemotherapy(all P＜0.05),In the control and low dose groups,NK cells changed more significantly after chemotherapy(P＜0.01).The percentages of CD3~+,CD3~++CD4~+,CD3~++ CD4~+/CD3~++CD8~+ of the low dose group and high dose group were higher than those of the control group before and after chemotherapy(all P＜0.05),the percentage of CD3~++CD8~+,CD3~++CD4~+/ CD3~++CD8~+ of the low dose group and hight dose group did not change notably(all P＞0.05). Conclusions The chemotherapy on patients with NSCLC will possibly cause malnutrition and immunosuppression.The benefits of giving 9-AA to NSCLC patients who were applying PPN and undergoing chemotherapy may include antagonizing immunological function aggravation,improving nutrition status and improving immunological functions of the T lymphocytes during chemotherapy.

Objective: To study the effects of Xanthnotoxol on contractility of isolated rabbit ileum and its relationship with Ca2+. Method: Routime experimental methods for isolated ileum were adopted. Result: Xanthnotoxol (XT) and Verapamil (Ver) inhibited the contraction of iso lated rabbit ileum smoth muscle induced by submaximal concentrations of acetylcholine　(ACh)　and serotonim　(5-TH), with a IC50 value (μmol*L-1) of 10.495±1.521,0.428±0.001and 18.132±1.627,0.249±0.003,respectively. XT and Ver inhibited the contraction induced by Ca2+after high K+ depolorization and for noncompetitively antagonist CaCl2 cumulative dose-response curve, the pD'2 value was 4.69±0.03 and 6.35±0.10, respectively. XT (10μmol*L-1)and Ver(0.06μmol*L-1)inhibited the contraction induced by ACh in Ca2+-free medium, while XT (100μmol*L-1)but not Ver(0.6μmol*L-1) inhibited the extracellar Ca2+-dependent contraction induced by ACh. Conclusion: XT has a calcium-antagonistic effect which was not similar to that of Ver.

OBJECTIVETo investigate the effect of amino acid parenteral nutritional (PN) support on serum tryptophan and melatonin in non-small cell lung cancer (NSCLC) patients receiving chemotherapy.

METHODSSeventy-two patients with inoperable NSCLC were divided into three groups randomly: control group, 250 ml/d amino acids PN therapy group and 500 ml/d amino acids PN therapy group. The same NP (cisplatin + vinorelbine) chemotherapy was carried out in all the three groups. During three sessions of chemotherapy,amino acids PN therapy was given to the amino acids PN therapy groups. Serum tryptophan and melatonin concentration changes were assessed before and after chemotherapy.

RESULTSAfter chemotherapy the concentration of MT and Try were much lower than that before chemotherapy in the three group patients (P < 0.05). But the concentration of MT and Try in the PN group patients was higher than that in control group patients. The concentration of MT and Try in the 500 ml/d amino acid parenteral nutritional support group patients were significantly higher than that in the 250 ml/d group patients, the difference was significant (P < 0.05).

CONCLUSIONAmino acid parenteral nutritional support is beneficial to improve the lower concentration of serum MT and Try in NSCLC patients receiving chemotherapy, and a more significant effect can be achieved by the 500 ml/d amino acid parenteral nutritional support treatment.

OBJECTIVETo deeply explore the effects of microcystins (MC-LR) on Bax and Bcl-2 during the course of MC-LR promoting liver tumor.

METHODSapplied to set up the animal model, and the effect of MC-LR promoting liver tumor was evaluated by the Albertgamma-GT methods. And then, the immunohistochemical technique, RT-PCR and image analysis were used to study the expression of the Bcl-2 and Bax during the course of promoting tumor.

RESULTS(1) MC-LR might enhance the positive reaction rate of GGT. The positive reaction rate of GGT in DEN + pure toxin group was 100%, it was significantly higher than the DEN control group 22.22% (P < 0.05). (2) The intension and areas of the protein expression of Bcl-2 in DEN + pure toxin group were 0.0977 and 0.0315, and in DEN control group were 0.0460 and 0.0205, respectively. The expression level of Bcl-2 protein in DEN + pure toxin group were significantly higher than in DEN control group (P < 0.05). Simultaneously, the protein expression of Bax was significantly decreased by MC-LR (P < 0.05). The intension and areas of the expression of Bax in DEN + pure toxin group were 0.0283 and 0.0073, and in DEN control group were 0.0655 and 0.0244 respectively. (3) The mRNA expression of Bcl-2 was significantly increased by MC-LR. The intension of Bcl-2 mRNA expression in DEN + pure toxin group was 2.244, being significantly higher than in the other groups (P < 0.05). However, the mRNA expression of Bax showed no significant difference between DEN + pure toxin and the other groups.

CONCLUSIONThe expression change of Bcl-2 and Bax should possibly play an important role in the course of MC-LR promoting liver tumor.

The rhizome of Panax japonicus var. major have been used as the natural medicinal agent by Chinese traditional doctors for more than thousand years. Most of the therapeutic effects of P. japonicus var. major had been reported due to the presence of tetracyclic or pentacyclic triterpene saponins. In this study, Illumina pair-end RNA-sequencing and de novo splicing were done in order to understand the pathway of triterpenoid saponins in this species. The valid reads data of 15. 6 Gb were obtained. The 62 240 unigenes were finally obtained by de novo splicing. After annotation, we discovered 19 unigenes involved in ginsenoside backbone biosynthesis. Additionally, 69 unigenes and 18 unigenes were predicted to have potential function of cytochrome P450 and UDP-glycosyltransferase based on the annotation results, which may encode enzymes responsible for ginsenoside backbone modification. This study provides global expressed datas for P. japonicus var. major, which will contribute significantly to further genome-wide research and analysis for this species.
