Objective　To make clear the expression,role and receptor polymorphism of γ/δ T cells in peripheral blood in systemic lupus erythematosus (SLE).Methods　Total γ/δ T cells,Vγ1 and Vγ9/Vδ2 subsets in peripheral blood of 12 normal controls,12 active and 12 stable SLE patients was examined by using cytometry assay.Then,peripheral blood mononuclear cells (PBMC) were stimulated with γ/δ specific antigen.TCR γ/δ receptor expression and Vδ2 chain CDR3 (complementary determination region) length display analysis were investigated further in these patients using SSCP method.Results　The number of γ/δ T cells were remarkably decreased in active SLE patients,and the γ/δ T cells did not show proliferation after antigen stimulation in SLE.Vδ2 was expressed in all of the SLE patients.CDR3 of Vδ2 genes was polyclonally displayed.Conclusion　This result adds more weight to the protective role of γ/δ T cells in SLE.It is postulated that γ/δ T cells might have deficient function and act as suppressor T cells.But it appears that there are no specific antigens that stimulate γ/δ T cells to proliferate leading to the occurrence of SLE.

Objective To investigate the causes and preventive measures of upper gastrointestinal bleeding in hyperbaric oxygen therapy for patients with severe closed head injury.MethodsThe clinical data of 24 cases of patients with upper gastrointestinal hemorrhage treated by hyperbaric oxygen therapy in the first people's Hospital of Fuyang District Hangzhou from May 2011 to May 2016 were analyzed, the occurrence time and clinical effect of upper gastrointestinal bleeding were analyzed.ResultsAmong the 24 cases of patients, 14 cases were treated for the first time that overt bleeding, including bleeding from the stomach liquid outflow of blood from 2 cases, gastric outflow 2 cases, hemorrhage after cure again received hyperbaric oxygen therapy 3 times again dominant bleeding 2 cases;6 cases hyperbaric oxygen treatment for third, 7, 10 times brown liquid or bloody fluid from the stomach outflow;4 cases hyperbaric oxygen treatment in patients with second and 3 courses of coffee liquid from the outflow tube, which accounted for 58.3%, 25.0%, 16.7% of the total, retrospectively;8 cases were with good recovery, 10 cases moderate disability, 4 cases severe disability, 2 cases vegetative state, 0 case died, the good recovery rate was 33.3%.ConclusionNot correctly grasp the time of hyperbaric oxygen therapy in the treatment of patients with severe closed craniocerebral injury will cause upper gastrointestinal hemorrhage, correct application of H2 receptor binding agent, developing targeted therapy programme can effectively prevent and treat upper gastrointestinal bleeding, so is worthy of the clinical's full attention.

Objective To observe the treatment of psoriasis vulgaris with narrow-band ultraviolet B and self-made traditional Chinese medicine fumigating.Methods A total of 100 patients with psoriasis vulgaris were randomly recruited into a treatment group and a control group,50 patients in each group.The control group was treated with narrow-band ultraviolet B:on this basis,the treatment group was treated with self-made traditional Chinese medicine fumigating.The therapeutic effeCts of both groups were observed.Results As compared with the control group.the treatment group showed better therapeutic effects(P<0.05).Conclusion It was effective to treat psoriasis vulgaris with narrow-band ultraviolet B combined with self-made traditional Chinese medicine fumigating.

Objective To study the effect of revised trauma score (RTS) in the rescue of patients with multiple trauma emergency application. Methods According to the admission time, 56 multiple trauma patients were assigned into the control group, and another 58 into the observation group. The control group was treated with traditional pre-hospital and hospital emergency care. The observation group with pre-hospital emergency care and hospital based on the RTS results. The two groups were compared in terms of effective treatment time and complications. Result The effective rescue time of the observation group was significantly shorter than that of the control group (P<0.001) and the complication rate was significantly lower than that of the control group (P<0.05). Conclusion Based on the integrated emergency rescue measures on the basis of RTS scores, accurate condition judgment can be made in a short time so that consistent care can be given to the patients and the success rate can be improved , and the occurrence of complications can be reduced and the rescue success rate can be increased.

Objective To introduce a new method for correction of epicanthal folds, which could avoid obvious scar in medial canthus. Methods First, through upper and lower palpebral margin incisions, the connective and orbicularis oculi muscle dense fibers underlying epicanthal folds as well as the superficial head of medial canthal ligament were thoroughly released and excised. After repositioning the medial canthus, the redundant skin tissue was removed and then the incisions closed. Results 122 epicanthoplasties had been performed. Postsurgical scars were invisible in all cases. All patients were satisfied with operation results. No recurrence of epicanthal fold was observed. Conclusions The introduced method has advantages in avoiding scar formation and is an especially suitable approach for epicanthoplasty in Asian patients.

To clarify the effects of zinc on the proliferation and apoptosis of cultured human retinal pigment epithelia (RPE) and the expression of caspase-3 in RPE cells. The effect of Zinc on the proliferation of RPE were examined with MTT method. TUNEL method was used to detect the apoptosis of RPE cells. Caspase-3 was detected by immunohistochemistry. A concentration of zinc higher than 0.001 microM could inhibit the proliferation of RPE. And the relationship between concentration of zinc higher than 10 microM and growth prohibition rate of RPE cells was dose-dependent. All concentrations of zinc including 0.001 microM enhanced the expression of caspase-3 of RPE. But only the concentration of zinc higher than 0.01 microM could induce apoptosis of RPE. It is concluded that zinc could enhance the expression of caspase-3 of RPE cells and induce apoptosis of RPE cells. Caution should be taken when using zinc supplements for the treatment of ARMD patients without deficiency of zinc.

Objective To observe the effects of hirudo capsules on degree of platelet activation and blood rheology in patients with cerebral arteriosclerosis. Methods 122 patients with cerebral arteriosclerosis were randomly divided into two groups by the random number table:observation group(61 cases)and control group (61 cases). The two groups received conventional treatment such as antihypertensive and hypoglycemic drugs,and 100 mg of aspirin once a day. In the observation group,additionally hirudo capsules 0.75 g,3 times a day were given. The therapeutic course in both groups was 2 months. Prior to the start of treatment and on the next day after the end of treatment,traditional Chinese medicine(TCM)clinical syndrome integral,platelet membrane glycoproteins caspase 1 (PAC-1),platelet adhesion molecule P selection(CD62P)positive rate,and blood rheology indexes were detected,in addition to the adverse reactions . Results Before treatment,there were no statistical significant differences between the two groups in terms of TCM clinical syndrome integral such as headache,dizziness,head fullness,multiple somnolence amnesia,lip dark purple,sublingual veins purple in color,PAC-1,CD62P positive rate,hemorheology indexes(all P>0.05). After treatment,TCM clinical syndrome integral PAC-1,CD62P,low shear viscosity,high shear viscosity,plasma viscosity and the hematocrit of two groups were significantly lower than those before treatment, the improvement in observation group being more remarkable〔headache:0.75±0.69 vs. 1.23±0.92,dizziness:0.96±0.78 vs. 1.54±1.24,head fullness:0.65±0.59 vs. 1.48±1.17,multiple somnolence amnesia:0.77±0.72 vs. 1.69±1.14,lip dark purple:0.83±0.81 vs. 1.32±0.79,sublingual veins purple:0.84±0.67 vs. 1.20±0.74, PAC-1:(10.31±4.57)%vs.(15.13±6.27)%,CD62P:(11.39±5.24)%vs.(16.40±7.91)%,low shear viscosity (mPa?s):7.52±3.37 vs. 8.97±3.50,high shear viscosity(mPa?s):4.35±1.12 vs. 5.58±1.19,plasma viscosity (mPa?s):1.54±0.35 vs. 1.88±0.42,hematocrit(HCT):0.43±0.09 vs. 0.49±0.10〕. In the patients' follow-up, there were no obvious side effects of hirudo capsules. Conclusion Hirudo capsule is a safe and effective drug for treatment of patients with cerebral arteriosclerosis as it is helpful in reducing platelet activation degree and improving the blood rheology indexes.
