Objective To investigate the effect of finger exercises on recovery of hand function and daily life ability in postoperative patients with bone trauma. Methods Ninety-eight phalanx trauma patients were equally divided into the treatment and control groups, those with odd admission number in the treatment group and those with even numbers in the control group: the control group was given postoperative routine care and the treatment group took finger exercises besides the routine nursing. The two groups were compared in terms of the treatment effect and the ability of daily life . Result The effective rate of the treatment group was higher than that of the control group and the ability of daily life was significantly better than that of the control group (all P < 0.05). Conclusion The postoperative finger exercises of the patients with bone trauma can increase the recovery of hand function , which is beneficial for the improvement their daily life ability.

Objective To explore the feasibility and significance of hand-assisted laparoscopic splenectomy (HALS) for ruptured spleen. Methods We conducted HALS in 18 cases of ruptured spleen between January 2002 and January 2003. According to the Buntain classification of CT-graded splenic injury, 7 cases were classified as “type Ⅱ” and 11 cases, “type Ⅲ”. Ruptured spleen was complicated by other organ injuries in 12 cases. Results The operation was completed successfully in 16 cases, the operation time being 75～115 min (mean, 92.5 min). A conversion to open surgery was made in 2 cases, which were suspected of having injuries of other major vessels. Postoperative time to normal activities was 20～30 days in 6 cases of simple ruptured spleen and 30～100 days in 10 cases of ruptured spleen complicating other injuries. Conclusions HASL is feasible for “type Ⅱ or Ⅲ” ruptured spleen without severe complicating injuries.

Objective To explore the feasibility and clinical efficacy of hand assisted laparoscopic splenectomy (HALS) for ruptured spleen. Methods From January 2002 to October 2002, HALS was performed in 12 cases, among whom were 8 cases combined with other viceral trauma. Results HALS was accomplished successfully in 10 cases and laparotomy in 2. In 10 cases, the operation time of HALS averaged 102.5 minutes. The mean post operative hospitalization was 5.8 days in 4 cases with only spleen trauma and 15.5 days in 6 combined with other viceral trauma. Conclusions HALS is a feasible, effective and safe surgical procedure for the cases with Buntain CT scalingⅡ or Ⅲ spleen trauma with no severe combined trauma.

IL-17,as a pro-inflammatory cytokine,is one of the early initiation factors of the inflammato-ry response induced by T cells.It can induce and regulate multiple immune responses.Recent studies have re-vealed that myeloid neutrophils,macrophage,mast cell and other innate immune cells all can secrete large a-mount of early responding IL-17 in organs suffering ischemia/hypoxia,and in turn can activate,amplify and re-cruit neutrophils to the reperfusion-damaged tissue to release large amount of free radicals and lysozyme that cause IRI.Researchers have also provided evidence that appropriate administration of anti-IL-17 mono-antibody to neutralize IL-17 during early reperfusion stage would reduce the tissue damage.The purpose of this review is to summarize the research progress of the effects of IL-17 produced by innate immunocyte on organ reperfusion injury.

Objective To Observe both curative and side effects of rhIL-11(recombinant human interleukin 11)in preventing and curing thrombocytopenia caused by chemotherapy.Methods From May 2003 to May 2004,research was done in the Department of Oncology,General Hospital of Shenyang Military Region by adopting double-blind placebo contrast and self cross-over study methods on 42 non-small cell lung cancer patients who had received GC chemotherapy.The effects of rhIL-11 and placebo on the minimal number of thrombocytes and their toxins were compared.24 hours later after the medicine for chemotherapy was given,rhIL-11 was administered hypodermically to the patients at the amount of 25 ?g/kg for 7 to 14 days.When the thrombocyte number was higher than 300?10~9/L,the administration of rhIL-11 was stopped.Results RhIL-11 could obviously increase the minimal number of thrombocytes during chemotherapy and reduce the times for blood transfusion.The side of rhIL-11 were mild edema,weariness and symptoms of catching cold.Conclusion RhIL-11 plays an obvious role in preventing and curing thrombocytopenia caused by chemotherapy,and has safe and definite curative effects without serious effects.

A questionnaire was taken in regard to the basic situation and study requirement for students of college training who want to get a university degree in the PLA.Some practical improvement was made and a preliminary model of physiological teaching for such students was established

Objective:To explore the effect of calcium release-activated calcium channel modulator 1 (ORAI1) on the migration and invasion of colon cancer cell line SW480 and its mechanism. Methods:The SW480 cells were infected with ORAI interference lentivirus. The expression of ORAI1 mRNA and protein was confirmed by quantitative real-time polymerase chain reaction and Western blot. Transwell chamber, adhesion, angiogenesis, and vasculogenic mimicry experiments were conducted to detect the ability of cell invasion, migration, and angiogenesis and the intercellular adhesion of homogeneous and heterogeneous cells among each group. Confocal microscopy was employed to detect the difference of store-operated Ca2+entry (SOCE) in each group. Western blott was used to detect the expression of ERK1/2, p-ERK1/2, MMP-2, VEGF, and E-cadherin protein. Results:After the infection of SW480 with the ORAI1 interference lentivirus for 72 h, significant fluorescence expression was observed. Compared with the empty vector group and control group, the expression of ORAI1 was lower in the interference group (P<0.01). Invasion and migration ability decreased (P<0.01); the intercellular adhesion ability of homogeneous cells increased (P<0.05); the intercellular adhesion ability of heterogeneous cells decreased (P<0.05);the angiogenesi and vasculogenic mimicry were enhanced (P<0.01);the internal flow peak of SOCE was low (P<0.05); the expression of p-ERK1/2, MMP-2, and VEGF proteins decreased (P<0.01); and the expression of E-cadherin protein increased (P<0.01). Conclusion:ORAI1 may promote the migration and invasion of SW480. This mechanism may be associated with the increase of SOCE.

Objective To investigate the expression and clinical significance of ABCG2 protein in hepato-cellular carcinoma (HCC). Methods Specimens of HCC were collected at The First Aifiliated Hospital of Sun Yat-sen University from January 2005 to December 2006. The expression of ABCG2 protein in 165 samples of HCC tissue, 25 samples of normal liver tissue and 40 samples of cirrhotic liver tissue was detected using immunohisto-chemistry. The correlation between the expression of ABCG2 protein and clinicopathological characters was then analyzed. Enumeration data, survival rate and the difference between groups were analyzed with a chi-square test, the Kaplan-Meier method and Log-rank test, respectively. Results ABCG2 protein expression was weakly posi-tive in all normal and cirrhotic liver tissues. In HCC tissues, the expression of ABCG2 protein was strongly positive in 66 cases and weakly positive in 99 cases. The expression of ABCG2 protein was related to tumor diameter, tumor number, adjacent organ invasion and TNM stages (χ2 =8. 130, 14. 279, 4. 820, 21. 179, P <0. 05). Kaplan-Meier survival analysis revealed that patients with strongly positive ABCG2 protein had a significantly lower 3-year overall survival (24. 1%) compared with those with weakly positive ABCG2 protein (39. 4%) (χ2 = 15.716, P<0.05). Conclusions The expression level of ABCG2 protein is related to tumor invasiveness, TNM stage and prognosis. ABCG2 has the potential to become a new target for HCC treatment.
