Objective:To investigate the effects of enteral immunonutrition on the intestinal barrier function and immune function in patients with severe pneumonia.Methods:Ninety patients with severe pneumonia were randomly divided into experimental group (n =45) and control group (n =45).All patients were received conventional therapy.In addition,patients in experimental group were given enteral immunonutrition,while patients in control group were given regular enteral nutrition.The changes of general conditions,intestinal barrier function index and immune function index were determined before treatment,on day 5 and 10 after treatment.The time of invasive mechanical ventilation,APACHE Ⅱ score and clinical effects of two groups were determined on day 10 after treatment.Results:Compared with those before treatment,in both groups,body temperature,respiration,heart rate,white blood cell count were all significantly decreased on day 5 and 10 after treatment (P ＜ 0.05).The above parameters were significantly lower in experimental group than control group on day 10 after treatment (P ＜ 0.05).The levels of serum ET,DAO were significantly decreased on day 5 and 10 after treatment in two groups compared with those before treatment (P ＜ 0.05),and these parameters were significantly lower in experimental group than control group(P ＜0.05).The number of CD3 and CD4 positive cell and the ratio of CD4 +/CD8 + were significantly increased on day 5 and 10 after treatment in two groups when compared with those before treatment (P ＜ 0.05),and these parameters were higher in experimental group than those in control group(P ＜ 0.05).The time of invasive mechanical ventilation,APACHE Ⅱ score were lower in experimental group than those in control group on day 10 after treatment (P ＜ 0.05).The rate of clinical response were higher in the experimental group than that in the control group on day 10 after treatment (P ＜ 0.05).Conclusion:Enteral immunonutrition is more effective in protecting the intestinal barrier function,improving the immune status,enhancing the immunity,reducing the time of invasive mechanical ventilation,and achieving the clinical effects of patients with severe pneumonia.

OBJECTIVETo explore the therapeutic effect of Pushen capsule (PSC) in treating primary hyperlipidemia.

METHODSTwo hundred and forty patients with primary hyperlipidemia were randomly divided into two groups, the 120 patients in the treated group treated with PSC (4 capsules, tid) and the 120 patients in the control group treated with Zhibituo tablet (3 tablets, tid), and they were administered at the same time with Zhibituo placebo. The therapeutic course for both groups was 4 weeks. The therapeutic effect and the effects on blood lipids and viscosity were observed.

RESULTSThe effective rate in the treated group was 76.3%, which was significantly higher than that in the control group (48.7%, P < 0.01). PSC showed a significant lowering effect on TC, TG and LDL-C and raising effect on HDL-C, and the effect in lowering TG was significantly better than that of Zhibituo (P < 0.01). PSC also showed a certain effect in decreasing whole blood viscosity of both high-sheared and low-sheared viscosity.

CONCLUSIONPushen capsule has promising blood lipid regulating effect in patients with hyperlipidemia, and some effects in lowering the blood viscosity.

OBJECTIVETo analyze the intermediate-term results associated with the use of Zweymtiller hip system.

METHODSReview the 116 cases (142 hips) who were treated with total hip replacement from 1996 to 2002 by a single surgeon using cementless Zweymüller hip systems.

RESULTSSixty-one cases (77 hips) were followed up, 50 cases (64 hips) were evaluated both clinically and radiographically while 5 cases (6 hips) and 6 cases (7 hips) were only evaluated clinically and radiographically respectively. The average follow-up period was 7.3 years (range 5 to 11 years). The mean preoperative Harris Hip Score was 46 while the mean postoperative Harris Hip Score was 93. Distal cortical hypertrophy and medullary sclerosis were observed in 30 hips (42.3%) and 33 hips (46.5%) respectively. Heterotopic ossification arose in 45 hips (63.4%). Radiolucent lines occurred in 27 stems (38.0%) but in no cups. Radiolucent lines were mostly observed in Gruen zones 1. Osteolysis occurred in 7 cups (9.9%) and 18 stems (25.4%). Osteolysis was mostly observed in Delee Zone 3 and Gruen zone 7. In the distal Gruen zones 3, 4 and 5, no radiolucent line or osteolysis was observed. No hips had been revised, 3 cups needed revision surgery because of aseptic loosening.

CONCLUSIONThe 5-11 years follow-up results are satisfactory, but osteolysis is common.

To investigate the effect of Protein kinase B on the expression and location of p21 in mouse early development. Immunopreciptation technology was used to detect the localization of p21 and Western blotting was used to analyze the expression of p21 after microinjecting mRNA of WT-PKB, myt-PKB and PKB-KD to mouse eggs. There was no obvious difference between the three kinds of mRNA in the expression of p21. But the cell localization altered. The p21 retain in cytoplasm after microjecting myt-PKB. In mouse fertilized egg PKB/Akt controls the cell cycle by changing the cell localization of p21.

BACKGROUNDKeyhole surgery has developed since the 1990s as a less invasive therapeutic strategy for intracranial lesions, initially for the treatment of intracranial aneurysms. The purpose of this study was to describe and evaluate the results of surgical treatment of lesions in the anterior fossa and sellar region via a supraorbital keyhole approach using eyebrow incisions.

METHODSBetween April 1994 and July 2003, 54 patients with lesions in the anterior fossa and sellar region were operated on via the supraorbital keyhole approach. The surgical results were studied retrospectively and compared with that of patients with lesions at the same locations but treated via a conventional subfrontal approach.

RESULTSNo significant difference in curative effect was found between the conventional subfrontal approach and the supraorbital keyhole approach. However, the supraorbital approach required a much smaller skin incision, causing less surgical trauma, while achieving excellent surgical exposure and good recovery.

CONCLUSIONThe supraorbital keyhole approach using an eyebrow incision is safe, effective, and both suitable and convenient for treating lesions in the anterior fossa and sellar region, with almost no adverse consequences on the facial features of patients.

OBJECTIVETo investigate the specific cytotoxity of tumor infiltrating lymphocytes (TIL) transfected with chimeric T cell receptor (CTCR) on cells which express KDR.

METHODSA recombinant retroviral plasmid (pMSCVneo-Vhgamma) was constructed by cloning VEGF121-hinger-FcRgamma (Vhgamma) into retroviral vector pMSCVneo. After packaging by PT67, the virus with high titer was used to infect TIL isolated from liver cancer tissues, and then MSCVneo-Vhgamma-TIL was generated. TIL infected with MSCVneo was used as a control. The cytotoxicty of the transgenic TIL on NIH3T3 and HepG2 expressing no KDR and on ECV304 and A375 expressing KDR was detected with MTT colorimetric assay.

RESULTSThe sequences of VEGF121 and hinger-FcRgamma were different from those reported, but the deduced amino sequences were identical to the reported ones. The cytotoxity of TIL infected with MSCVneo on target cell was similar to that of the control TIL; both only had mild cytotoxity on cancer cell line. No significant cytotoxity was found in TIL infected with MSCVneo-cTCR on NIH3T3, but its cytotoxity on ECV304 was significant. The cytotoxity on HepG2 was similar to that of MSCVneo-TIL and uninfected TIL, but cytotoxity on A375 was significantly higher.

CONCLUSIONChimeric T cell receptor permanently grafts TIL cell with predefined new specificity. TIL expressing Vhgamma can selectively recognize and kill vascular endothelial cell and tumor cells which express VEGF receptor KDR.
