Objective To investigate the value of virtual colonoscopy in the diagnosis of malignant and benign lesions in the colon. Methods CT colography was performed in 37 patients. Patients included 20 cases colon polyps, 6 cases colon cancer, 4 cases diverticulum, 5 cases ulcerative colitis and 2 cases other benign lesions. The colon lesions were evaluated with 2D and 3D images, depending on individual software. Results were compared with colonoscopy for each case. Results 17 cases colon polyps, 6 cases colon cancer, 4 cases diverticulum, 2 cases ulcerative colitis were detected by CTC. Conclusion CT virtual colography is a promising technique for the detection of colorectal lesions. This procedure is minimal invasive and fast, causes mild patient discomfort.

Objective To evaluate the effect of various herniorraphy in treating inguinal hernia. Methods The clinical data of 108 patients who underwent conventional Bassini herniorraphy (BH), tension free herniorraphy (TH), or laparoscopic herniorraphy (LH),respectively were analysed and comparated. Results The operation time in TH was less than that in BH, and in LH was longer than that in TH. The ability recovery, hospita stay and postoperative complication in TH and LH were less than those in BH.All the patients were followed up for at least 1 year.Of them, 1 recurred after BH, but there was no recurrence after TH and LH. The blood neutrophils, serum level of fibrin, C-reactive protein and alpha-1 antitrypsin increased significantly in the patients undergoing herniorraphy, which were significantly higher in the patients underwent TH and LH. Conclusions The curative effect of TH and LH is much better than that of BH in treating ingumal hernia. Application of marlex for herniorraphy might increase inflammation response, but it will not increase the incidence of infection.

Objective To construct 1.3-fold-overlength infectious clone of hepatitis B virus isolated from Chinese patients , observe the expression of plasmid in Huh7 of liver cancer cells and establish genome of HBV in vitro. Methods HBV DNA in serum was extracted from HBV patient. SOE-PCR was performed to produce a 1.3-fold-overlength genome of HBV. The plasmid was named pHBV1.3 (C). After that,pHBV1.3 (C) was transfected into Huh7 cells, HBV related viral antigens and DNA were detected by ELISA,Western Blot and Fluorescence quantitative PCR. Furthermore, adefovir dipivoxil, a clinic anti-viral drug, was utilized to test the sensitivity of the new infectious clone. Results An infectious clone of pHBV1.3 (C) was successfully constructed. HBV gene carried in pHBV1.3 (C) could be efficiently replicated and expressed in Huh7 cells. Adefovir could inhibit HBV replication in this HBV cell model. Conclusions A recombinant plasmid containing 1.3-fold-overlength of HBV genotype C was successfully constructed. This construct is competent to support viral transcription and replication in vitro , suggesting that infectious cells are expected to be a new model of HBV infection in vitro.

Objective To investigate the clinical characteristics of the tympanic membrane atelectasis and treatment methods ,and to provide a reference value for future clinical diagnosis and treatment .Methods A retro‐spective analysis of 86 patients(104 ears) with tympanic membrane atelectasis treated in our hospital from June 2011 to August 2013 .Disease severity was classified according to the erasmus classification of atelectasis by Sade ,and pre- and post -operative air -bone gaps (ABG) were compared .Results There was no statistical difference of mastoid gasification on CT scan between mild and sever tympanic membrane atelectasis (P>0 .05) .While the sta‐tistical difference was found in two groups of whether there were soft tissues in middle ear and mastoid cavity on CT scan(P<0 .05) .There was an improvement in the average ABG for all stages .Conclusion This study demonstrated that surgical intervention had a favorable effect on hearing level across all stages .The treatment of atelectatic ears should be taken and individualized .

Objective To observe the effects ofXiaotan Sanjie Decoction on ultramicrostructure in MKN-45 human gastric cancer orthotopic xenograft;To discuss its mechanism for gastric cancer. Methods MKN-45 human gastric cancer cell line was used to establish subcutaneous tumor model in nude mice as an experimental model which passed three generations of tumor source. Then OB glue was used to establish human gastric cancer orthotopic xenograft model. 40 model nude mice were divided into control group, model group (received gavage with saline),Xiaotan Sanjie Decoction group (received garage withXiaotan Sanjie Decoction) and Tegafur group (received gavage with Tegafur), 10 mice in each group. Mice in the control group were under normal diet, without medicine intervention. After 6 weeks of treatment intervention, tumor weight was detected, inhibitory rate was calculated, the ultrastructural changes of gastric cancer cells were detected through transmission electron microscopy.Results The tumor weight inXiaotan Sanjie Decoction group was significantly lower than that in control group and model group (P<0.05,P<0.01). The tumor inhibition rate was 46.2%. Under the electron microscope, MKN-45 gastric cancer cells strain changed to typical apoptosis.ConclusionXiaotan Sanjie Decoction can lead to apoptosis effects on MKN-45 human gastric cancer orthotopic xenografts. All evidences indicate that inducing apoptosis may be one of the most important mechanisms ofXiaotan Sanjie Decoction in treating gastric cancer.

Objective To investigate the influence of internet addictive disorder(IAD) patient' s family cohesion and adaptability effect with Satir family therapy.Methods According with table of random number,the patients (n =120) with IAD were divided into two groups,test group with the 60 patients and the control group with 60.All of subjects were given Linyi mental health center conventional interventions,test group with satir family therapy and the control group without the therapy.Measurements with the addiction self-test scale and the family cohesion and adaptability scale for five months before and after the intervention.The differences of the two groups were analyzed,and then the correlation analysis were used.Results After the intervention of the test group with Satir family therapy,compared to control group,the IAD score (54.28 ± 4.69) and family ideal cohesion (74.64 ±3.22),real cohension (70.42 ± 3.66),ideal adaptability (54.08 ± 5.78),cohesion dissatisfaction degree (5.07 ±1.64) and adaptability dissatisfaction degree (2.23 ± 0.85) score were all had statistically significant (P ＜ 0.05 or 0.01).IAD score,ideal cohesion,real cohension,ideal adaptability and real adaptability score,before and after the intervention between the control group and the test group had statistically significant (P ＜ 0.05 or 0.01).Conclusion The Satir family therapy can improve family cohesion and the adaptability,and also effectively improve the parent-child relationship.

The aim of this work was to investigate guar gum/ethylcellulose mix coated pellets for potential colon-specific drug delivery. The coated pellets, containing 5-fluorouracil as a model drug, were prepared in a fluidized bed coater by spraying the aqueous/ethanol dispersion mixture of guar gum and ethylcellulose. The lag time of drug release and release rate were adjustable by changing the ratio of guar gum to ethylcellulose and coat weight gain. In order to find the optimal coating formulation that was able to achieve drug targeting to the colon, the effect of two independent variables (the ratio of guar gum to ethylcellulose and the coat weight gain) on drug release characteristics was studied using 3×4 factorial design and response surface methodology. Results indicated that drug release rate decreased as the proportion of ethylcellulose in the hybrid coat and the coat weight gain increased. When the ratio of guar gum to ethylcellulose was kept in the range of 0.2 to 0.7, and the coat weight gain in the range of 250% to 500%, the coated pellets can keep intact for about 5 h in upper gastrointestine and achieve colon-specific drug delivery. The pellets prepared under optimal conditions resulted in delayed-release sigmoidal patterns with T5% (time for 5% drug release) of 5.1-7.8 h and T90% (time for 90% drug release) of 9.8-16.3 h. Further more, drug release was accelerated and T90% of the optimum formulation pellets decreased to 9.0-14.5 h in pH 6.5 phosphate buffer with hydrolase. It is concluded that mixed coating of guar gum and ethylcellulose is able to provide protection of the drug load in the upper gastrointestinal tract, while allowing enzymatic breakdown of the hybrid coat to release the drug load in the colon.
