Objective To observe the comprehensive effect of different drugs for ectopic endometrium after laparoscopic surgery.Methods According to random number,75 intrauterine membrane patients with endometriosis treated by laparoscopy were divided into control group(25 cases),mifepristone group(25 cases)and gestrinone group (25 cases).The patients of the control group were not taken medication,the patients of mifepristone group in postop-erative clothing were treated with mifepristone,the patients of gestrinone groups in postoperative plus gestrinone treat-ment.All of the patients were taken 6 months treatment,therapy,pregnancy rates,and adverse reactions of three groups were observed.Results The total effective rate of the control group was 76.0%,which of the mifepristone group was 96.0%,the difference between the two groups was statistically significant (χ2 =4.15,P <0.05),which of the gestri-none group was 92.0%,and the difference between the two groups was statistically significant(χ2 =2.38,P <0.05). The incidence rate of side effects in mifepristone group was 12.0%,which was lower than 36.0% of gestrinone group,the difference was statistically significant (χ2 =8.39,P <0.05 ).The patients combined infertility were 17 cases,after the treatment for pregnancy 8 cases,the cumulative pregnancy rate of mifepristone group was 66.7%, which was higher than 20.0% of gestrinone group,and the difference was significant (χ2 =4.15,P <0.05).Conclusion Simple using abdominal mirror operation treatment uterine within film different bit syndrome patients of effect not too ideal,but operation through taking meters non -division ketone or pregnancy three ketone can obviously improve treat-ment has efficiency,reduced recurrence rate,while can increased pregnancy rate and reduced patients of bad reaction occurred rate,is a security efficient of treatment programme,worth promotion in the clinical treatment.

Objective To investigate the correlation between behavioural and psychological symptoms and cerebral white matter lesions (WMLs) in patients with Alzheimer's disease (AD). Methods Sixty patients with AD aged more than 60 years (AD group) and 40 age-, sex-matched subjects with normal cognitive function (control group) were recruited. data of cerebral CT were analyzed blindly. The sum of WMLs in 8 regions, such as bilateral frontal region, parieto-occipital region, temporal region, and subtentorial region, etc were used as the total score of WMLs, and the cerebrovascular lesions revealed on CT were detected. The AD group was assessed with the Neuropsychiatric Inventory (NPI). Results There were significant differences in total WML score (1. 450 ±2. 310 vs. 9. 640 ± 1. 566, P =0. 000), left frontal WMLs (0. 340 ± 0. 340 vs. 1. 720 ± 0. 248, P = 0. 001), fight frontal WMLs (0. 310 ±0. 560 vs. 1. 680 ±0. 312, P =0. 001), left parieto-occipital WMLs (0. 240 ±0. 360 vs. 1. 550 ±0. 244, P =0. 012), right parieto-oecipital WMLs (0. 140 ±0. 230 vs. 1. 450 ± 0. 231, P = 0. 006) and cerebrovascular lesions (0. 120 ± 0. 330 vs. 2. 230 ± 0. 378, P = 0. 002) hetwsen the AD group and the control group. Spearman correlation analysis showed that NPI was correlated with the total WML score (rs =0. 487, P = 0. 016), left frontal WMLs (rs =0. 490, P = 0. 014), right frontal WMLs (rs = 0. 502, P = 0. 014), left parieto-occipital WMLs (rs =0. 507, P =0. 012) and right parieto-occipital WMLs (rs =0. 521, P = 0. 014), and it was not correlated with the cerebrovascular lesions (rs = 0. 132, P = 0. 590).Conclusions WMLs and cerebrovascular lesions are essential in the onset of AD and disease development. WMLs are closely correlated with the behavioural and psychological symptoms in patients with AD.

Objective To explore the expressions and the roll of p63mRNA and murine double minute 2(MDM-2) protein in esophageal squamous cell cancer and the prognosis of the cancer.Methods The expressions of p63mRNA and MDM-2 protein in 38 cases of esophageal squamous cell carcinoma tissues and the corresponding esophageal normal tissues were detected using reverse transcriptase polymerase chain reaction(RT-PCR) and immunohistochemistry. Results The positive rates of deltaNp63 mRNA in all malignant and normal tissues were 63.5% and 52.63% respectively,without significant difference.The expression of the DeltaNp63 mRNA was significantly higher in low differentiated group than in well and moderate differentiated group,without significant difference in age,gender,lymph node metastasis and clinical stage.Only 1 of 38 cases of esophageal squamous cell carcinoma tissues presented TAp63 mRNA expression and all esophageal normal tissues had no TAp63 mRNA expression.The positive rates of MDM-2 protein in esophageal squamous cell carcinoma tissues and normal tissues were 65.79% and 5% respectively,with significant difference.The expression level of the MDM-2 protein was higher significantly in low differentiated group than in well and moderate differentiated group,with significant difference in clinical stage and without significant difference in age,gender and lymph node metastasis.The DeltaNp63 mRNA expression in the esophageal squamous cell carcinoma tissues was positively related to MDM-2 protein expression.Conclusion The major isotype expressed in the esophageal cancer and epithelia is DeltaNp63,which may play an important role in the carcinogenesis,development and prognosis of the esophageal squamous cell carcinoma.TAp63 is not the major isotype expressed in the esophageal cancer and epithelia,and not related to the carcinogenesis of esophageal squamous cell carcinoma.High expression of MDM-2 protein is associated with the carcinogenesis of esophageal squamous cell cancer and related to the prognosis of esophageal squamous cell carcinoma.DeltaNp63 regulates the cell cycle and apoptosis through the pathway of MDM2 and causes the carcinogenesis of esophageal squamous cell cancer.

Objective To investigate expressions of microRNA-21 (miR-21),PTEN,NF-κB,and caspase-9 in colon carcinoma and their possible mechanisms in progression of tumor.Methods Expressions of above-mentioned indexes and percentage of apoptotic cells in colon carcinoma,colon adenoma,and normal tissue specimen were detected.Results Expressions of miR-21,PTEN,N F-κB,and caspase9 in normal tissue were 0.39 ±0.02,50％,25％,and 50％.Expressions of them in colon adenoma were 0.62 ±0.06,50％,35％,and 55％,and those in colon carcinoma were 0.88 ±0.04,30％,75％,and 20％.Percentage of apoptotic cells were (24.64 ± 7.66) ％,(15.86 ± 1.44) ％,and (6.20 ± 2.57) ％,respectively.The above P-values were all less than 0.05.Expression of miR-21 was positively correlated with TNM stage,depth of infiltration,differentiated level and expression of NF-κB while inversely correlated with PTEN and caspase-9 expressions and percentage of apoptotic cells.The r-values were 0.647,0.297,0.259,0.519,-0.299,-0.388,and-0.931,respectively.Conclusions Hyperexpression of miR-21 participated in progression of colon carcinoma probably through down-regulating expressions of PTEN and caspase-9 and up-regulating expression of NF-κB and then suppressing cell apoptosis.

Objective To investigate the influences of blast wave overpressure created by explosion on rat's blood-brain barrier (BBB),and to provide an experimental evidence for further elucidating the mechanism of craniocerebral blast injury,to help direct the clini- cal therapeutic strategy.Methods Twenty male Sprague-Dawley rats were randomly divided into four groups:15min,12h and 24h post- explosion groups and normal control group with five rats for each group.Rats were injured with blast wave produced by explosion.Evan 's blue(EB)was intravenously injected into the injured rats,and the overpressure-induced leakage of BBB was examined under the fluores- cence microscope and by quantitative observation with opacimeter.Results Extensive impairment of BBB could be seen all over the brain 15 min after the overpressure explosion,and bright red EB fluorescent patches appeared as a method distributing along the capillary vessels. These patches were more distinct near the cerebral cortex,and with the lapse of time,their number decreased gradually from the inner to the outer areas.The changes in EB contents in brain tissue matched with that of the BBB.The EB contents in brain tissues in 15min group were(330.4?53.6)?g/g,and it was much higher compared with that of other groups(P

A comparative study of systemic lupus erythematosus in 39 male(MSLE) and 120 female (FSLE) patients was carried out. The results showed that, in MSLE, the mean age at the time of disease onset was similar to FSLE, and the clinical features were nearly the same as those in females, except that the first signs of MSLE were less complicated than those of FSLE, malar rash occurred less commonly in MSLE than in FSLE(P

Objective To study the effect of a selective COX-2 inhibitor Celecoxib on cell proliferation and apoptosis of human coloretal cancer cell line HT-29 to seek an effective and safe drug for colon cancer chemoprevention. Methods Using MTT assay, flow cytometry(FCM), acridine orange and ethidium bromide staining, the effect of celecoxib on the proliferation and apoptosis of HT-29 cells were investigated. Results The growth of HT-29 cells was inhibited by celecoxib in a dose- and time- dependent manners. FCM analysis showed that the treated HT-29 cells had typical Sub-G 1 peak, the apoptotic rate of which was (7 31?2 37)%～(48 3?2 86)%. The cell ratio of G 0/G 1 phase increased, whereas the cell ratio of S and G 2/M phases decreased after treatment, which was in a dose-dependent manner as well. The treated HT-29 cells exhibited some morphological features of apoptosis, including cell shrinkage, nuclear condensation, DNA fragmentation, and the formation of apoptosis bodies, the apoptotic index of which was in a dose- and time- dependent manners. Conclusions Celecoxib inhibited proliferation and induced apoptosis of human colorectal cancer cell line HT-29, which may be related to blocking the cell cycle progress of HT-29 cells.

Objective To summarize the experience of using anastomotic apparatus and ring in the reconstruction of alimentary tract after gastrectomy. Methods Anastomotic apparatus or anastomotic ring was used to reconstruct alimentary tract after total or partial gastrectomy including esophagojejunostomy, esophagogastrostomy, gastroduodenostomy, gastrojejunostomy and jejunojejunostomy. Results The reconstruction of alimentary tract after gastrectomy using anastomotic apparatus and ring was successfully completed once in 182 cases. There were not anastomotic leakage, bleeding and infection after operation. During the follow-up period of 3～12 months, gastroscope or barium meal examinations showed that only 3 cases had the stricture of anastomotic entrance, and the other patients recovered well. Conclusion Compared with using traditional manual anastomosis to reconstruct alimentary tract after gastrectomy, anastomotic apparatus and ring had the advantages of convenience, simplicity, rapidity and reliability, and could raise operative efficiency greatly, shorten operative time and prevent the complications of post-operation such as the leakage and striture of anastomotic entrance. Using anastomotic apparatus and ring was recommended in the reconstruction of alimentary tract.

Objective To compare the effect of myomectomy and uterine artery embolization in the treatment of uterine fibroids .Methods 158 patients who were pathologically diagnosed uterine fibroids were randomly divided into the uterine artery embolization group and myomectomy group ,79 cases in each group .The blood loss 3 days after operation,pelvic pain and pressure symptoms ,hospitalization time,follow-up and time of normal activity were recorded and compared.Results The pelvic pain,pressure symptoms,hospitalization time,cure rate,incidence rate of compli-cations and recurrence rate of the two groups had no statistically significant differences ( t=1.21,0.97,1.06,χ2 =0.98,1.21,1.32,all P>0.05).The postoperative bleeding score ,time of return to normal activity in the uterine artery embolization group were (5.8 ±0.5) points,(9.8 ±1.8) d,which were better than those of the myomectomy group[(4.9 ±0.4)points,(25.9 ±5.1)d](t=3.76,5.98,all P<0.05).Conclusion The effect of the myomec-tomy and uterine artery embolization treatment for uterine leiomyoma is similar ,and both have high efficiency and safe-ty,but the uterine artery embolization treatment has less impact on the body of patients .
