Gene therapy of spinal cord injury (SCI) is the most promising method compared with the others, because it doesn't involve the problems of resource and higher exclusion which respectively exists in fetal nerve transplantation and peripheral nerve transplantation. There are two ways of gene therapy to be chosen: one is to transfer objective genes to the target-cells in vivo directly; the other is to transfer objective genes to one proper kind of transplantable cells firstly, then graft the highest expressing cells to the target-cells in vivo. To realize the transfer of genes to cells, two measures are used in common: physical or chemical measure such as micro infection et al and biochemical measure i. e. gene modified defective virus. Although there are some questions unresolved in this field, the clinical value of gene therapy of SCI in the future is depended.

Objective To evaluate therapeutic effects of hyperthermia therapy in combination with chemotherapy for the treatment of nonsmall cell lung carcinoma. Methods Fifty-two patients with non-small cell lung carcinoma underwent hyperthermia therapy in combination with chemotherapy(NP regimen) in this hospital between September 2003 and November 2006.The therapeutic effects were evaluated after 3 cycles of the combination therapy,and were compared with those from 16 patients receiving only chemotherapy between January 2006 and November 2006.Results The combination therapy offered significantly better curative short-term effects than the simple chemotherapy.The total response rate was 65.4%(34/52) for the combination therapy and 37.5%(6/16) for the simple chemotherapy(Z=-2.419,P=0.016).Significant pain relief was achieved in patients after the combination therapy,while no analgesic effect was noted after the simple chemotherapy,the difference between the two groups of patients being statistically significant(Z=6.486,P=0.000).There was no significant difference in the incidence of complications between the two groups,which mainly included nausea,granulocytopenia,thrombocytopenia,and abnormal liver functions.Conclusions Hyperthermia therapy in combination with chemotherapy compares favorably to simple chemotherapy in the treatment of non-small cell lung carcinoma.

Objective To explore the influence of intravesical chemotherapy combined with hyperthmia on levels of insulin growth factor( IGF) and tumor necrosis factor( TNF) in bladder cancer after operation. Methods 64 cases of transitional cell carcinoma of bladder accepted TURBt were randomly divided into two groups: intravesical chemotherapy combined with hyperthmia group and intravesical chemotherapy group. Levels of ICF and TNF in two weeks before therapy 、two weeks after therapy, four weeks after therapy were tested. Results The IGF levels were (65.97±5.25)μg/L,(49.93±1.98)μg/L,(36.82±1.89)μg/L in intravesical chemotherapy combined with hyperthmia group and(61.87 ±5.41)μg/L, (57.86 ±2. 18) μg/L, (48. 68 ±2. 26) μg/L in intravesical chemotherapy group. The TNF levels were(2.32 ±0. 36)μg/L, (3. 84 ±0. 31) μg/L, (8. 79 ±0. 46)μg/L in intravesical chemotherapy combined with hyperthmia group and(2. 21 ±0. 19)μg/L,(2. 89 ±0.47) μg/L, (3. 87 ±0.61)μg/L in intravesical chemotherapy group. The influence of intravesical chemotherapy with hyperthmia on levels of IGF and TNF were significant than intravesical chemotherap, and the influence degree showed in time-dependent manner (all P ＜ 0. 05 ). Conclusion Intravesical chemotherapy combined with hyperthmia had curative effect in inhibiting the recurrence of tumor after operation.

[Summary] The article reported 107 cases of bile duct residual stones treated by plasma shock wave lithotripsy with inverse flush under fiber choledochoscope via T-tube fistula.Of the 107 patients, stones were completely removed in 98 patients, and residual stones remained in 9.Intraoperative biliary hemorrhage occurred in 5 cases, which were stopped after spraying the norepinephrine . There were 4 cases of arhythmia , 13 cases of subcostal or upper abdominal pain , and 11 cases of abdominal distention and diarrhea , all of which were cured by symptomatic treatment .Postoperative biliary infection occurred in 7 cases, which were cured by anti-infection and biliary drainage.Except for 1 patient of lost of follow-up, 106 patients were followed for 6 months.Ultrasound and CT examinations showed free of calculus in 101 cases, and intrahepatic bile duct residual stones in 5 cases.We deem that plasma shock wave lithotripsy combined with reverse flushing under fiber choledochoscope is a minimally invasive , safe, and effective treatment for difficult biliary residual stones .

Objective To investigate that whether the immuno-modulatory capacity is intact in myelodysplastic syndrome-refractory anemia (MDS-RA) derived mesenchymal stem cell (MSCs) and what are the differences compare with those from normal donors.Methods Isolating MSC from MDS and normal donors respectively and exam their differences on T lymphocyte activation,proliferation and suppression.Results The results showed that the capacity of suppressing T cell proliferation and activation is weakened.Conclusion We propose that MSCs from pathological environment might be abnormal and should not be used for autologous transplantation.

Objective To evaluate the effect of Caspase-1 inhibitor on hepatic tissue and on the expression of hepatic interleukin-18 of rats with experimental severe acute pancreatitis(SAP).Methods Forty-two SD rats were randomly assigned into 3 groups: healthy control group(HC,n=6),SAP+normal saline group(SAP-S,n=18) and SAP+ICE inhibitor group(SAP-ICE-I,n=18).SAP was induced by retrograde infusion of 4% sodium taurocholate into the pancreaticobliliary duct in SD rats.Animals in HC group received similar surgical procedure and duct cannulation but without sodium taurocholate inoculation.In SAP-S group,rats received the first intraperitoneal injection of isotonic saline 2 hours after induction of acute pancreatitis,and the same injection was repeated at 12th hour.ICE inhibitor was injected into the rats in SAP-ICE-I group 2 hours after induction of acute pancreatitis,and the same injection was repeated at 12th hour.Blood samples were obtained from the rats in SAP-S and SAP-ICE-I groups via cardiac puncture at 6,12 and 18h after modeling,respectively.The levels of serum amylase(AMY),alanine aminotransferase(ALT) and aspartate aminotransferase(AST),and the peritoneal fluid,were detected at these three time points.The histopathology of pancrease and liver were observed under light microscope.Intrahepatic expression and localization of IL-18 protein were detected respectively by Western blotting and immunohistochemistry.Results Serum AMY,ALT,AST and peritoneal fluid were significantly increased in SAP-S and SAP-ICE-I groups compared with those in HC group(P

Objective To explore the feasibility of nasolabial sulcus flap transfer with autologous free skin graft to repair the alar defects after malignant tumor resection.Methods From January 2012 to January 2015,9 patients with malignant tumor were treated in the hospital.After complete tumor removal,the defect area being reconstructed was 1.5 cm × 1.3 cm to 2.5 cm × 2.5 cm.The defects of 9 patients were all restored with nasolabial sulcus flap combined with autologous free skin graft.Results The 9 patients were followed up for 6-18 months postoperatively.The nasolabial sulcus flap and autologous free skin graft were survived completely in all cases.Symmetrical alae were noted with slight edema within nasal cavity but without difficult ventilation.Scar was repaired in phase-two surgery.Conclusions Nasolabial sulcus flap combined with autologous free skin graft is an optional way in alar defects restoration.Further with secondary morphologic plasty,satisfactory surgical outcome can be achieved.

Objective To evaluate the diagnostic value of transbronchial lung biopsy (TBLB) via bronchoscope for lung diffuse lesions and peripheral pulmonary lesions. Methods The results of TBLB were retrospectively analyzed from 256 diagnoses of unknown patients with lung diffuse lesions or peripheral lung lesions. Results Eighty-nine final diagnosis cases via TBLB only once, the diagnostic rate of double lung diffuse lesions was the highest, [51.06% (24/47)], local non-nodule lesions, nodule lesions, cavity lesions were 33.33%(23/69), 29.91%(35/117), and 28.57%(4/14), respectively. Among 24 diagnostic cases of double lung diffuse lesions, there were 6 cases of pneumonia of pulmonary tuberculosis, 9 cases of lung carcinoma, 7 cases of adenecarcinoma; 6 cases of pneumonia, 2 cases of fungous infection, and 1 case of lung hemosiderusis. The diagnostic yield about 58 cases of local lesions was low, among which non-nodule lesions accounted for 33.33% and nodule lesions accounted for 29.91%. In 89 cases of peripheral lung lesions with histological diagnosis, lung carcinoma and pulmonary tuberculosis were frequent diseases, which accounted for 86.52%. Conclusion TBLB is a reliable, safe, effective and repeatable operation method in diagnosis of lung diffuse lesions and peripheral pulmonary lesions.

ObjectiveTo analysis the subsets of the lymphocyte and dendritic cells (DC) in peripheral blood in patients with neurosyphilis and investigate the relationship between these cells and onset of neurosyphilis.MethodsThe subsets of CD4+T cells as well as DCs and the counts of CD4+T and CD8+T were analyzed by flow cytometry with immunofluorescent staining in 8 patients with neurosyphilis and 10 healthy controls.ResultsIn peripheral blood of neurosyphilis patients the proportion of CD4+T cell was significantly higher than that in the normal controls ( P<0.01); the proportion of CD8+T cell was significantly lower than that in the normal controls ( P<0.05). The proportion of Th1, Th2 and the ratio of Th1/Th2 in neurosyphilis patients was (14.12±5.12)%, (1.52±0.88)% and (12.05±5.62), respectively. In normal controls, it was (26.10±4.98)%, (0.99±0.35)% and (31.62±16.62) respectively. The expression of Th1 and the ratio of Th1/Th2 in neurosyphilis patients was significantly lower than the normal controls (P<0.05). The proportion of DC1 and DC2 in neurosyphilis patients was not significantly different from that in normal controls ( P>0.05). There was a significant correlation between DC1 and Th1, DC2 and Th2 in the neurosyphilis patients ( P<0.051), but no correlation between the proportion of DCs and the ratio of Th1/Th2 ( P>0.05).ConclusionThe cellular immune function of neurosyphilis patients may be inhibited, and there is no relationship between the proportion of DCs subset and unbalance of Th1/Th2.
