Objective To explore effect of psychological intervention on negative automatic thoughts,self acceptance and social support for patients with type 2 diabetic cataract.Methods Patients with diagnosed type 2 diabetic cataract(n=105)were divided into the research group(56 cases)and the control group(49 cases).The centrol group received routine treatment.The research group was given psychological and behavioral intervention based on routine treatment.They underwent evaluation by negative automatic thoughts questionnaire (ATQ),self-acceptance questionnaire(SAQ)and social support rate scale(SSRS)before intervention and in the 2th and 6th weeks after intervention.The results were subsequendy analyzed. Results ATQ score of the research group in the 2th and 6th weeks were lower than that of the control group(P＜0.05).ATQ score,total SAQ score,score of SA and SD factors,total SSRS score and score of objective support,subjective support and utilization of support were all lower than those before intervention from the 2th week in the research group.While these happened in the control group only in the 6th week(P＜0.05).Total SAQ score and score of SA and SD factor were lower than those of the control group(P＜0.05).Total SSRS score and score of objective support,subjective support and utilization of support were lower than those of the control group(P＜0.05).Relative analysis showed total score of social support and its factors was negatively related with ATQ score,but was positively related with SAQ score and score of SA and SD factors(P＜0.05).Conclusions Psychological and behavioral intervention could reduce the negative automatic thoughts,allevinte self acceptance and increase social support degree for patients with type 2 diabetic cataract.

Objective To summarize the experience of diagnosis and management of regional portal hypertension. Methods The clinical manifestations, diagnostic methods and therapeutic modalities of 16 cases of regional portal hypertension were analyzed retrospectively. Results Among 16 patients with ~regional portal hypertension, 12 cases resulted from pancreatic diseases, and 4 cases were complicated with non-pancreatic diseases. The main clinical findings were splenomegaly in 16(100%), abdominal pain ~in 10(63%) , gastrointestinal bleeding in 7(44%) and abdominal masses in 3(19%). All had normal liver function test. The main diagnostic methods were ultrasonography(US), computerized tomography (CT) and endoscopy. Splenic vein thrombosis could be detected by color Doppler ultrasonography (7/7). ~Enhanced CT could demonstrate enlarged and tortuous short gastric veins, gastroepiploic veins, and ~coll- ~ateral vessels around splenic hilum(16/16). Isolated gastric varices (4/5) were revealed mainly by ~gastro- ~scopy . Splenectomy was effective for controlling gastrointestinal bleeding, and its complication of portal vein thrombosis occurred in 1 case. Conclusions It is not difficult to diagnose regional portal ~hyper- ~tension based on findings of US and CT, together with special clinical characteristics. Therapeutic options should be ~individualized according to underlying diseases, however, splenectomy should be performed in the ~patients with gastrointestinal bleeding.

Objective To compare the histological effects of 1.44-?m and 1.06-?m pulse Nd:YAG laser radiation on stomach wall tissues in dogs. Methods Five beagle dogs were enrolled in this study to received 1.44-?m(experiment group) and 1.06-?m(self-control group) pulse Nd:YAG laser radiation at the posterior wall of the stomach.Totally 19 dosage of radiation was used including a 0-mJ radiation.The dosage of every single pulse was 200,500,or 800 mJ,and the amount of the pulses was 1,5,10,20,40 or 80.The experiment was repeated for 5 times.Afterwards,the injured tissues was obtained and observed under a light microscope and the photomicrograph was taken at the meantime.Results In experimental groups,the widest and photoevaporated zone and coagulation zone were(1863.8?225.0) ?m and(885.1?82.9) ?m,and the deepest photoevaporated zone and coagulation zone were(1787.4?93.7) ?m and(1327.8?86.3) ?m,respectively;which were significantly higher than those in the control [widest and photoevaporated zone and coagulation zone:(576.8?30.8) ?m and(1275.8?140.1) ?m,t=12.672,P=0.000 and t=-5.366,P=0.001;deepest photoevaporated zone and coagulation zone:(105.0?16.3) ?m and(994.8?130.0) ?m,t=39.539,P=0.000 and t=4.773,P=0.002;respectively].Conclusions 1.44-?m Nd:YAG laser is suitable for vaporization and coagulation in stomach surgery.It shows higher ability in vaporization but lower ability of coagulation than 1.06-?m pulse Nd:YAG laser radiation,which,however does not affect the outcomes of wound cleansing and hemostasis.

These types of anti-angiogenesis drugs have become a hotspot in the field of breast cancer research.

Background and purpose:Hereditary nonpolyposis colorectal cancer(HNPCC) which related to inheritance is an autosomal dominant inheritance.There are many screening standards differing presently from country to country.The Amsterdam standard is internationally recognized.These screening standards are just based on family history and clinical manifestations which can not reflect the essence of the disease.At present,the golden standard for screening HNPCC is mismatch repair genes detection that is in the experimental stage.The purpose of this study was to investigate the expression of mismatch repair genes hMSH2 and hMLH1 in HNPCC and their clinicopathological signif icance,and to fi nd a simple,fast and economic method for screening HNPCC.Methods:Immunohistochemical staining was used to detect the expression of hMSH2 and hMLH1 in 20 cases with HNPCC(Group A),20 cases with ordinary hereditary colorectal cancer(Group B),20 cases with sporadic colorectal cancer(Group C),and 20 cases with colorectal polyps(Group D).Results:The expression rates of hMSH2 and hMLH1 in Group A,B,C and D were 35%(7/20),70%(14/20),95%(19/20) and 100%(20/20) respectively,which illustrated that the probability of HNPCC and the negative expression of hMSH2 and hMLH1 was reduced from Group A to Group D.There were signifi cant differences among these groups(P0.05).Conclusion:The negative expression of hMSH2 and hMLH1 was signifi cantly correlated with HNPCC and location and differentiation of colon carcinoma.Immunohistochemical staining may be useful for screening HNPCC.

Objective To establish the high myopic choroidal neovascularization (CNV) in guinea pigs and to investigate the role of (matrix metalloproteinase-2,MMP-2) and tissue inhibitor-2 of metalloproteinase (TIMP-2) in high myopic CNV.Methods Seventy-two 2-week-old guinea pigs were randomized into control group (n =36) and high myopia group (n =36).Right eyes were indued form deprivation high myopia for 6 weeks.Thirty guinea pigs were randomly selected in each group,and CNV were induced in the right eyes br the 532 nm laser.MMP-2 and TIMP-2 expressions were investigated by immunohistochemistry pre-laser and 7,14,21,28,35 days after laser induction,respectively,while MMP-2 and TIMP-2 relative expression levels in retinal pigment epithelium (RPE)-choroid-sclera complex were detected by real-time PCR.Integral opitical density (IODs) of positive expression and mRNA relative expression levels of these factors were performed by statistical analyses.Results The expressions of MMP-2 and TIMP-2 were up-regulated in the two groups after laser photocoagulation through immunohistochemistry and real-time PCR examinations.Expression of MMP-2 peaked at 21 d and TIMP-2 at 28 d,respectively.IODs of positive expression and mRNA relative expression levels of MMP-2 were higher in high myopia group than those in control group at each inspective time point,and the differences were statistically significant (P ＜ 0.05).TIMP-2 expression was significantly reduced in high myopia group compared with control group before laser photocoagulation (P＜0,05),while there was no significant difference between the two groups at each time point after laser photocoagulation.Conclusions MMP-2 and TIMP-2 were closely related to the formation of high-myopic CNV.Balance disorders of MMP-2 and TIMP-2 might participate in the occurrence and development of high-myopic CNV.

The lymphatic metastasis affects prognosis and survival of colorectal cancer seriously,and lymphangiogenesis plays an important role in the lymphatic metastasis. Many factors such as COX-2 and MMP-7 which are found in many researches recently can promote the expression of VEGF-C which can promote the lym-phangiogenesis by connecting with its receptor and activating the relevant signal pathway. At present,as these related factors of lymphangiogenesis are found in colorectal cancer,the process of lymphangiogenesis in colorec-tal cancer becomes more clear,but the exact mechanism of these factors needs to be researched in future.

Objective To evaluate the effects of hypothermic cardiopulmonary bypass (CPB) on rocuronium-induced neuromuscular blockade in the patients undergoing open heart surgery.Methods Twenty ASA physical status Ⅰ or Ⅱ patients,scheduled for elective open heart surgery,aged 18-45 yr,with body mass index of 18-25 kg/m2,were randomly assigned into 2 groups (n =10 each) using a random number table:room temperature group (group R) and hypothermia group (group H).The nasopharyngeal temperature was maintained at 30-31 ℃ during CPB in group H or at 36-37 ℃ during CPB in group R,and it was maintained at 36-37 ℃ before and after CPB in both groups.Anesthesia was induced with iv etomidate 0.3 mg/kg,fentanyl 2-4 μg/kg and rocuronium 0.3 mg/kg.The patients were tracheally intubated and mechanically ventilated.Anesthesia was maintained with iv infusion of sufentanil and intermittent iv boluses of midazolam and fentanyl.BIS value was maintained at 40-60.Neuromuscular block was monitored using TOF-WATCH SX accelerometer.Train-of-four stimulation (intensity 40 mA,frequency 2 Hz,wave length 0.2 ms,interval 12 s) of ulnar nerve was used.Rocuronium was infused intravenously using an automatic feedback control system to maintain T1 at 8％-12％.At 10 min after start of operation (T0),10 min after onset of CPB (T1),and 10 min after termination of CPB,blood samples were collected for determination of the plasma concentration of rocuronium (by HPLC).The infusion rate and consumption of rocuronium were recorded before,during and after CPB.Results Compared with group R,the plasma concentration of rocuronium was significantly decreased at T1,2,and the infusion rate and consumption of rocuronium were decreased before and after CPB in group H.Conclusion Hypothermic CPB enhances rocuroniuminduced neuromuscular blockade in the patients undergoing open heart surgery.
