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.

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 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.

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.

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.

BACKGROUND:Mesenchymalstem cels have pluripotent differentiation, and can promote cel engraftment and immune regulation. Therefore,we attempt to use human umbilical cord mesenchymal stem cels as anew source for treatment of lung cancer by exploringcelisolation, identification and transplantation combined with chemotherapyforlung cancer in mice.
OBJECTIVE:To investigate the isolation and identification of human umbilical cord mesenchymal stem cels and its transplantation combined with chemotherapy for lung cancer inmice.
METHODS:Human umbilical cord mesenchymal stem cels were isolated from fresh umbilical cord of newborns and identified using tissue culture and enzyme digestion. Twenty Balb/C nude mouse models of lung cancer were randomly divided into two groups:mice in chemotherapy group were given chemotherapy, and those incombinedgroup given combination of chemotherapy with human umbilical cord mesenchymal stem cel transplantation.
RESULTS AND CONCLUSION:Compared with the chemotherapy group, the gastrointestinal tract was rosy and shiny, intestinal mucosa was smooth and complete, and tumor mass and blood indexes significantly decreased in thecombinedgroup (P< 0.05). To conclude, mature human umbilical cord mesenchymal stem cels can be obtained by tissueculture and enzyme digestion, andthecel transplantation combinedwith chemotherapy can significantly reduce gastrointestinal tract damage and themake peripheral hemogram in a stable level.

BACKGROUND:So far the positive or negative effects of mesenchymal stem cel s on tumor growth and metastasis are under discussion. OBJECTIVE:To explore the mechanism of bone marrow mesenchymal cel s in promoting lung cancer metastasis. METHODS:Primary rat bone marrow mesenchymal stem cel s were obtained by direct adherence method of the whole bone marrow, and differential adherence combined with digestion control method was performed to purify cel s. Lung cancer cel lines were cultured, and the effects of bone marrow mesenchymal stem cel s on the migration, invasion and metastasis of lung cancer cel s were observed by scratch test, cel invasion and migration assays. Orthotopic lung cancer models were established in rats and bone marrow mesenchymal stem cel s were seeded onto the left lung of rats. Then, pathological changes of lung tissues were observed at 14 days after transplannation. RESULTS AND CONCLUSION:After the scratch test, the migration rate of lung cancer cel s became higher, and the scratches healed with time. And after cel transplantation, the number of migrated lung cancer cel s increased, as wel as the ability of lung cancer cel s penetrating the Matrigel was strengthened. Besides, fibrous connective tissues could be found around the lung cancer tissues, and necrosis with distinct boundary and large tumor nuclei;the metastatic tissues showed obvious infiltration and necrosis with large tumor nuclei. These results suggest that bone marrow mesenchymal stem cel s can promote the invasion, migration and metastasis of lung cancer cel lines.

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.

The instantaneous changes of the body cavities under the impact of blast waves were studied in three dogs. The changes were recorded with the high-speed photography of three different speeds (563, 1526, and 6526 frames/second). It was demonstrated that there was an 11.7% reduction on average of the body cavities due to compression after 0.777 kg/cm2 of overpressure was received.In correlation with the authors' previous research work and with the relevant literature, it is believed that the 11.7% reduction is likely related to the severe pulmonary injury which is resulted from the abrupt disturbance of hemodynamics after blast wave impact.
