Objective To study the changes and clinical significance of glutathione redox-state in patients with coronary heart disease (CHD). Methods Based on both with or without atherogenic risk factors and the result of coronary arteriography, 118 patients were calssified into three groups: control group( n =30) ,risk group(n =28) and CHD group (n =60). Venous blood sample was obtained, then the plasma reduced glutathione ( GSH) and oxidized glutathione (GSSC) were measured by using glutathione reductase recycling method. Redox potential(EhCSH/GSSG) was calculated using Nernst equation. According to clinical situation,CHD group was divided into two subgroups:un-stable angina pectoris( UAP) group(n = 32) and acute myocardial infarction (AMI) group (n =28). Results From control group to risk group,then to CHD group,GSH gradually decreased,and there was significant difference between CHD group and control group (P < 0.05 ) , but GSSG and EhGSH/GSSG gradually increased, there was significant difference between CHD group and risk group and control group (P < 0. 05). There was no significant difference be-tween the UAP subgroup and AMI subgroup in GSH,GSSG and EhGSH/GSSG(P >0.05). Conclusions Body's an-tioxidant capacity decreases and the oxidative stress exists in artherosclerosis, and furthermore there is a certain degree of relevance between oxidative stress and hyperlipoidemia,all these show that improving this situation may decelerate or prevent the formation and progress of artherosclerosis.

AIM: To investigate the effect of lowering intraocular pressure ( IOP ) and side effect of travoprost ( TA ) on phacoemulsification and intraoclular lens ( IOL ) implantation in primary open-angle glaucoma ( POAG) .
METHODS: Patients with POAG already received surgery of phacoemulsification and IOL implantation were selected by randomized, single - blind, parallel group trial. TA was applied once a day in 43 patients (43 eyes) of treatment group and brinzolamide was used twice in 43 patients ( 43 eyes ) of control group. All patients were observed for 12wk. IOP, ocular symptom and adverse reaction etc. were observed.
RESULTS: The daily average IOP ( mean ± standard deviation) in the treatment group decreased from (24. 20±3.01)mmHg (1mmHg=0.133kPa) to (16.77±2.89)mmHg and that in the control group was from ( 23. 87±3. 47 ) mmHg to ( 18. 81± 3. 07 ) mmHg. IOP pre- and pro-treatment within two groups had significant difference ( P<0. 01), IOP between the groups at each time point had statistical difference (P<0. 05). Conjunetival congestion increased and itching in treatment group was obviously more serious than that in the control group, but the treatment could continue. No other ocular and systemic adverse events related to the drugs were found.
CONCLUSION: It is demonstrated that travoprost is highly effective and safe in reducing IOP in POAG already received surgery of phacoemulsification and IOL implantation.

Objective To study the clinical significance of urinary mtcroprotems examination on early diagnosis of kidney damage of children with obesity. Method Urinary microproteins were tested in 40 obese children by enzyme - linked immunosorbent assay and 50 healthy children as controls. Results Urinary microprotem examination were abnormal in 8 obese children. Albumin in 5 cases increased, and transferrin(TRF) with retinol-binding protein in 1 case increased meanwhile. TRF in 3 cases increased. One case was abnormal by kidney biopsy.Conclusion Urinary microprotem examination was the sensitive index in early diagnosis of obesity-related glomerulopathy in children.

Objective To investigate the influence of mycophenolate mofetil(MMF) on blood and urine biochemical indica‐tors as well as the expressions of IL‐1 in anti‐glomerular basement membrane(GBM ) nephritis SD rats .Methods The SD rats were randomly divided into control group ,model group and MMF group .And then the models of SD rat anti‐GBM nephritis were estab‐lished by injecting rabbit anti‐SD rat GBM serum antibodies .The urinary protein and blood parameters were detected initially ,1st , 2nd ,3rd and 4th weeks after administration respectively .The expressions of IL‐1 and TGF‐β1 were detected by Elisa Kit and the re‐nal pathological changes were observed by HE and PAS staining .Results After treatment for 4 weeks by MMF ,the 24 h UP ,BUN and SCr levels were lower in MMF group than those of the model group(P<0 .05) .And the expressions of IL‐1 and TGF‐β1 were decreased in MMF group .The results of HE and PAS staining showed that in model group rats ,glomerular tuft morphology was destroyed and inflammatory cell infiltration was observed in the glomeruli .Some glomeruli had cellular crescent formation .Infiltra‐tion of inflammatory cells was also observed in the interstitium .MMF clearly improved these pathological changes overall ,with im‐provements noted in both glomerular and tubular degeneration as well as in the infiltration of inflammatory cells .Conclusion MMF shows certain renal protective effect on anti‐GBM nephritis SD rats .

Objective To study and assess clinical application of two Nickel-Titanium(NiTi)rotary instru- ments,namely ProTaper and Hero 642,in preparation of root canals.Methods 125 teeth were divided into three groups and respectively instrumented by stainless K-files,ProTaper or Hero 642 rotary instruments.All teeth were obturated with lateral condensation method.The efficiency of preparation and obturation was analyzed with radio- graphs.Results NiTi rotary instruments were better in keeping the curvature and flow of curved canals than stain- less K files.There was no transportation,apical blockage and ledge in NiTi groups.The operative time was shorter and endodontic flare-up seldom occurred in NiTi groups.Conclusion The NiTi rotary instrumentation technique could be used to prepare curved root canals effectively and quickly.The future use of NiTi engine-driven rotary in- strument appeared to be promising.

Objective To compare the clinical effects between uniportal video-assisted thoracic surgery (VATS) and 3-portal VATS lobectomy for patients with lung cancer. Methods Patients were divided into uniportal VATS lobectomy group (n=45) and 3-portal VATS lobectomy group (n=53). The clinical data were compared between two groups, including the oper-ation time, intraoperative blood loss, number of lymph node dissection, length of incision, postoperative extubation time, post-operative pain score and postoperative hospitalization. Results There were no significant differences in intraoperative blood lose (128.75±18.32) mL vs (129.15±17.69) mL, lymph node dissection number (13.33±1.05) vs (13.12±1.38), duration of chest drainage (4.90±0.75)d vs (4.75±0.70)d, duration of hospital stay (7.52±1.16)d vs (7.55±1.10)d and incidence of seri-ous postoperative complications between two groups (P>0.05). The incision length (5.36±0.22)cm vs (7.44±0.35)cm, numeric pain intensity scale including first day(6.47±0.54) vs (6.86±0.52),third day(3.59±0.29) vs (4.05±0.25), and patient satisfac-tion scores (91.03 ± 2.62) vs (88.35 ± 2.97) were significantly better in uniportal VATS group than those of 3-portal VATS group (P<0.05). The operation time (143.81±17.97) min vs(130.11±15.03)min was longer in uniportal VATS group than that of 3-portal VATS group (P < 0.05). Conclusion Uniportal VATS lobectomy is safe and reliable for patients with early-stage lung cancer, which has less surgical injury, slighter pain, and higher satisfaction than 3-portal VATS lobectomy.
