Objective To investigate the signal transduction of bFGF to regulate the colorectal carci- noma cell growth via PI3K/PKB pathway.Methods MTT assay was used to determine the suppressive effect of bFGF on the growth rate of LoVo cell;(?-~(32)P)ATP incorporation assay was used to detect the increased activity of PKB in LoVo cell;the RT-PCR technique was used to test the expression of cyclin A;Western Blot analysis was used to detect the expressions of PKB and cyclin A protein.Results When the bFGF worked on the LoVo cell at various times,it was found that the PKB activity of the LoVo cell was increased by the(?-~(32)P) ATP incorporation assay.By preprocessing by the depressor-LY294002 and bFGF,the activity of PKB was sig- nificantly reduced(P

Objective To evaluate modified Soave procedure for the treatment of Hirschsprung's disease for the neonate and infant. Methods Seventeen cases of short and sigmoid types of Hirschsprung's disease were treated by transanal modified Soave procedure. The incision was made 1cm posterioly and 2-3 cm anterioly above the dental line; the dissection progressed from the submucosa layer up to the perineal reflex into the pelvic cavity, and the rectum was pulled through. "V" shap muscular cuff was excised on the posterior wall. The proximal colon was anastomosed to the anal mucosa. Results Mean operative time was 160 min ? 45 min, mean blood loss was 45 ml ?35 ml. No enterocolitis, anastomotic leak, perianal infection and anastomotic stenosis occurred. All patients recovered with normal defecation, and no complication was observed from a follow-up of more than 4 mos. Conclusion Modified Soave procedure is safe and effective for the treatment of Hirschsprung's disease in the neonate and infant.

0.05).Maxillary incisors were easily to be affected,especially the maxillary central incisor.Crown fracture was the most common traumatic type.The combination of dental trauma and oral and maxillofacial soft tissue injury was experienced by 692 patients(71.0%).Conclusion: Dental trauma was one of the common diseases in oral emergencies.Knowledge of the etiological and clinical characteristics of emergency dental trauma could help us to treat them and make specific preventive measures.Clinical examination should be comprehensive and meticulous to avoid misdiagnosis,for emergency dental trauma often involving multiple teeth,and associated with different degrees of maxillofacial soft tissue injury.

Objective To evaluate the clinical value of magnifying chromoscopy in combination with Kudo criteria in detection and diagnosis of colorectal lesions. Methods After conventional electronic colonoscopic diagnosis of 125 colorectal lesions, staining and magnifying observation by chromoscopy were made with Kudo criteria, and biopsy specimen and resected samples were sent for pathologic examinations. Results The accuracy of ordinary colonoscopy and magnifying colonoscopy compared with histological diagnosis of inflammatory polyps, tubular adenomas, villous adenomas and colorectal cancer was 95.62%, 80%, 90% and 100% respectively and 100%, 93.75%, 92.86% and 100% respectively. The overall accuracy of two procedures was 85.6% and 95.2% respectively. Conclusions Magnifying chromoscopy is valuable in detection of tiny and slightly elevated colorectal lesion, and has high efficacy in judging the nature of lesions with Kudo criteria.

OBJECTIVE:To provide reference for standardizing dispensing and use of intravenous drug. METHODS:266 piec-es of intravenous drug instructions were collected in PIVAS of our hospital,and then the labeling information were statistically ana-lyzed,including dispensing method,diluted or dissolved solvent before preparation and storage time after preparation. RESULTS:Among 266 intravenous drug instructions,there were 45 kinds of finished product infusion varieties and 221 kinds of drugs needing to be prepared. Among these,there were only 30 pieces of drug instructions with labeling dispensing method,accounting for 13.57%;195 pieces of drug instructions stated solvent for dilution and 22 stated solvent for dissolution before preparation,account-ing for 88.24% and 19.13%;69 pieces of drug instructions stated storage time,accounting for 31.22%. CONCLUSIONS:The la-bel information of dispensing method and storage time in intravenous drug instructions is markedly insufficient or not clear. Drug ad-ministration departments are suggested to strengthen the instruction standardization management. Meanwhile,manufacturers should specify the relevant information in intravenous drug instructions.

Objective To investigate whether intraoperative hypotension was associated with postoperative delirium in older patients undergoing laparoscopic surgery with prospective cohort study.Methods Study subjects were patients,＞ 65 years of age,undergoing laparoscopic surgery,who were enrolled in an ongoing prospective observational study of the pathophysiology of postoperative delirium.Intraoperative blood pressure was measured,and predefined criteria were used to define hypotension.Delirium was measured by the Confusion Assessment Method on the first two postoperative days.Data were analyzed with t-test,two-sample proportion test,and ordered logistic regression muhivariable model,including correction for multiple comparison.Results Data from 213 patients with a mean age of 73.6 years (SD 6.1) were studied.Of these 63 (29.6％) developed delirium on day 1 and 61 (28.6％) on day 2.Relative hypotension (decreases by 20％,30％,or 40％) or absolute hypotension [mean arterial pressure (MAP) ＜ 50mmHg] were not significantly associated with postoperative delirium,nor was the duration of hypotension (MAP ＜ 50 mmHg).Conversely,intraoperative blood pressure variance was significantly associated with postoperative delirium.Conclusions These results showed that increased blood pressure fluctuation,not absolute or relative hypotension,was predictive of postoperative delirium.

Objective To perform Low dose dynamic MSCT( multi-slice CT) in sleeping obstructive sleep apnea syndrome ( OSAS) patients correcting the imprecise measure values in waking state, and to exactly analyse the location and extension of the dynamic changes about the condition. Methods Sixteen OSAS patients were scanned both in waking and naturally sleeping period ( end phase of inspiration and expiration). Measured at the narrowest part of the retropalatal ( RP) and retroglossal ( RG) and 5 mm under the tip of epiglottis at the epiglottal ( EPG) at the end period of inspiration in sleeping, respectively, and compared the accurate pos(?)on of the narrowest or occlusive level in 3 phases. All patients were also scanned using cine mode at the narrowest level at the end period of inspiration in sleeping to show the pharyngeal cavity changes during sleep. Results The smallest XSA of RP region (Mw = 47. 50 mm2 ,Me =73. 00 mm2 , Mi =2. 00 mm2 ;Zwe =2. 897,Pwe =0. 003 ;Zwi =4. 192,Pwi

Purpose:To identify clinical predictors of stage ⅢA-N2 in patients with non-small cell lung cancer. Methods:From March 1995 to February 1998, 118 patients with pathological stage ⅢA-N2 non-small cell lung cancer who underwent a resection by Shanghai Chest Hospital were analysed. Prognostic factors were estimated from the date of operation using the Kaplan-Meier and log-rank analysis. The Cox regression model evaluated the influence of factors on the survival. Results:The overall of 3-year and 5-year survivals of the 118 patients were 40.5% and 18.4%. Margin, the number of N2 lymph nodes and stations, the cycles of adjuvant chemotherapy were associated with survival. In a multivariate analysis, the number of N2 lymph nodes and the cycles of adjuvant chemotherapy significantly influenced survival. Conclusions:The number of N2 lymph nodes and the cycles of adjuvant chemotherapy were important prognostic factors of stage ⅢA-N2 non-small cell lung cancer.
