Objective To investigate effect of irinotecan combined with cisplatin on level of Bcl-2 and MACC1 protein in serum in patients with cervical cancer.Methods 92 cases of patients with cervical cancer surgery from department of gynaecology and obstetrics,the third People’s hospital of Nanchang were randomly divided into control group and treatment group.Control group was treated with paclitaxel therapy chemotherapy, treatment group were treated with irinotecan combined with cisplatin.Bcl-2 and MACC1 protein in serum were compared before and after the treatment. Results The level of Bcl-2 and MACC1 in both groups were not statistically significant pre-treatment;After treatment, the levels of Bcl-2 and MACC1protein in serum were decreased (P<0.05).Compared with control group post-treatment, the level of Bcl-2 and MACC1 protein in serum were lower in treatment group (P<0.05).During follow-up, death cases of treatment group and control group were 5 cases and 6 cases respectively, the survival rate of 89.13% and 86.96% respectively within the past six months(χ2 =0.103,P>0.05).Death cases of treatment group and control group were 4 cases and 12 cases respectively. the survival rate of 91.30% and 73.91% respectively within one year (χ2 =4.84, P <0.05 ) Conclusion Irinotecan combined with cisplatin in the treatment of cervical cancer in one year survival rate is higher, which may be related to the decrease of serum levels of Bcl-2 and MACC1 protein content.

Objective: To compare the ocular parameters of acute angle closure glaucoma (AACG) and chronic angle closure glaucoma (CACG). Methods: Totally 106 patients with primary angle closure glaucoma were recruited: 58 patients with AACG and 48 with CACG. All patients were divided into 3 groups: AACG attack eyes group, AACG uninvolved fellow eyes group and CACG group and underwent the same ophthalmic examinations, comprising optometry, keratometry, and A-scan ultrasonography. The lens/axial length factor (LAF) and relative lens position (RLP) were calculated. Results: The AACG attack eyes had a significant shallow anterior chamber depth, thick lens, short axial length and larger LAF. hTere tended to be a reduction in the percentage of LAF>0.20 in AACG attack eyes, CACG eyes and AACG uninvolved fellow eyes, though there were no statistically signiifcant difference in all groups (P>0.05). Conclusion: The eyes with AACG attack have a more crowded anterior chamber structure compared with uninvolved fellow eyes and eyes with CACG.

Objective To observe the clinical efficacy of Qishen Yiqi Dropping Pills combined with telmisartan on early diabetic nephropathy with Qi deficiency and blood stasis syndrome and changes of oxidative stress indicators. Methods Sixty patients with early diabetic nephropathy of qi-yin deficiency and blood stasis syndrome were randomly divided into treatment group (30 cases) and control group (30 cases). Both groups were given diabetes education, diabetes diet control and insulin injection. Patients in the control group took telmisartan orally, and patients in the treatment group were given Qishen Yiqi Dropping Pills additionally. The treatment course was 12 weeks. The indicators were observed before and after treatment including blood pressure (BP), fasting blood glucose (FBG), glycated hemoglobin (HbA1c), urinary albumin excretion rate (UAER), urinary 8-iso-PGF2α excretion rate, serum superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and malonaldehyde (MDA), and the clinical efficacy was evaluated. Results The total effective rate of the treatment group was significantly higher than that of the control group, with statistical significance (Z=2.822, P=0.005). After treatment, the indicators including BP, FBG, HbA1c, serum MDA, UAER and urinary 8-iso-PGF2α excretion rate all decreased significantly in both groups (P<0.05). Serum SOD and GSH-Px increased significantly at the same time (P<0.05). BP, FBG and HbA1c were not statistically different between the two groups (P>0.05). However, serum MDA, UAER, and urinary 8-iso-PGF2αexcretion rate were significantly lower (P<0.05), and serum SOD and GSH-Px were significantly higher in treatment group than control group (P<0.05). Conclusion Qishen Yiqi Dropping Pill combined with telmisartan is effective in reducing proteinuria in patients with early diabetic nephropathy of qi-yin deficiency and blood stasis syndrome. Its protective mechanism for kidney is possibly related to inhibiting oxidative stress injury at the early stage of diabetic nephropathy.

Aim To purify monoclonal antibody in mouse ascites by a modified membrane affinity chromatography(MAC). Methods Human serum albumin HSA was adsorbed on the zeta-bind membrane (ZBM), a positively charged nylon membrane filter. Then the mouse aecites containing mAbs were filtrated through the ZBM to cause the mAbs bind to HSA adsorbed on ZBM. Finally,the purified mAbs were dissociated from the ZBM with guanidine hydrochloride solution. Results A sheet of ZBM(diameter 50mm) absorbed with HSA filtrated by 10 mL ascites could reach its maximum mAb binding capacity after two rounds of re-fitration. The dissociation of mAb from ZBM need only one round of filtration of dissociating solution. The purified mAb displayed a single band after PAGE. Sensitivity of detedcting HSA with purified mAbs was 20-fold higher than that with unpurified ascites in dot innunogold filtration assay(DIGFA). Conclusion The modified MAC with ZBM is a much easier, time-saving and effective method for affinity purification of antibodies in ascites.

Objective To investigate the clinic features of extra-intestinal manifestations ( EM ) of ulcerative colitis (UC) in Chinese patients in Liao ning Province. Methods Two hundred and five UC cases in the First Hospital of China Medical University from Jan. 2002 to Feb. 2007 were reviewed retrospectively. Chi-square test was used to test the difference between groups. Results Skeletal and mouth manifestation were the most frequent extra-intestinal manifestations (6. 83% ). The incidence of parenteral performance in patients less than 40 years old was significantly higher than that in patients more than 40 years old (P <0. 01). There was no significant difference between male and female ( P > 0. 05). Our data showed that the extensive colitis had the highest incidence of extra-intestinal manifestations than of the other two types, LUC and DUC. Most extra-intestinal manifestations presented in UC active period ( P < 0. 05 ). The incidence of extra-intestinal manifestations in severe cases was significantly higher than that in mild cases(P <0. 05). There was a trend of increasing frequency from mild to moderate to severe type cases ( P < 0. 05 ). The occurrence of extra-intestinal manifestations was significantly higher in the group with disease course more than five years than that with less than five years group ( P < 0. 05). Conclusions Extra-intestinal manifestations had a high incidence in UC. The most frequently involved organs were joints, mouth, hepatobiliary, skin and eyes system. The patient could have multiple extra-intestinal manifestations and there was a tendency that EM was more likely occurred among patients in the higher age, active phase, longer course, severity degree of the disease.

Objective To investigate the clinical efficacy of superficial needling plus external washing with Chinese herbal medicine in treating post-stroke shoulder-hand syndrome.Methods Sixty patients with post-stroke shoulder-hand syndrome were randomly allocated to treatment and control groups, 30 cases each. The treatment group received superficial needling plus external washing with Chinese herbal medicine and the control group, conventional acupuncture. Pain severity was assessed using the visual analogue scale (VAS) and upper limb function was assessed using the Fugl-Meyer Assessment (FMA) of motor recovery in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 96.7% in the treatment group and 83.3% in the control group; there was a statistically significant difference between the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in the VAS score and the FMA score in the two groups (P<0.05). There were statistically significant post-treatment differences in the VAS score and the FMA score between the treatment and control groups (P<0.05).Conclusion Superficial needling plus external washing with Chinese herbal medicine is an effective way to treat post-stroke shoulder-hand syndrome.

Objective To investigate the impact of different irrigation time on oxygenation in-dex and acid-base balance during percutaneous nephrolithotomy(PCNL).Methods Forty patients un-dergoing selective PCNL were included in this study,were divided into two groups:group S,irrigation time<120 min(n=22);group L,irrigation time≥120 min(n=18).PaO2/FiO2 ,pH and BE were determined before and after irrigation,CVP were recorded before irrigation and every 20 min during irrigation. Results The CVP maximum value were higher in group L than that in group S during irrigation (P <0.05).The PaO2/FiO2 were lower after irrigation than that before irrigation in group L(P<0.05).The pH and BE were lower in group L than that in group S after irrigation(P<0.05).Conclusion Irrigation fluid absorption is observed during PCNL.That can provoke oxygenation function decline and metabolic ac-idosis with irrigation time extend,the operation time properly shortened.
