Objective To study the diagnosis and treatment of acute gangrenous cholecystitis in senile (patients), so as to decrease complications and lower the mortality rate. Methods The clinical data of 112 senile patients with acute gangrenous cholecystitis were retrospectived analysed.Results 19 cases(17.0%) of the 112 patients had hyperpyrexia, 8(7.1%) had icterus,11(17.0%) had a mass in the right upper abdomen, 26(23.2%) had symptoms of peritonitis; 11(9.8%) were complicated with acute edematous pancreatitis, 5(4.5%) had acute obstructive suppurative cholangitis, 6(5.4%) had septic shock. All of the 112 patients underwent surgery. At operation, 79 of 95 cases of acute calculous cholecystitis had (gangrene) of gallbladder,16(16.8%) had gangrene with perforation; in 17 cases with acute non-calculous cholecystitis had gangrene of gallbladder, 9(52.9%) had gangrene with perforation. Of the 112 patients, 86 underwent cholecystectomy, 18 underwent partial cholecystectomy, 5 underwent cholecystectomy with bile duct exploration and T tube drainage, and 3 underwent cholecystostomy 104 patients(92.9%) were cured, 8 patients(7.1%) died, and 9(8.7%) of the 104 cured patients had postoperative complications. (Conclusions) Acute gangrenous cholecystitis in senile patients should be definitely diagnosed as soon as (possible), co-existent diseases should be correctly treated, emergency operation should be performed with in 24 hours of onset of symptoms(or in the shortest time after admission), and a suitable operation should be (selected).

Objective To investigate the differences in expression of hypoxia-inducible factor-1? (HIF-1?) in placental trophoblasts between normal pregnancy and pregnancy-induced hypertension (PIH) and the relationship of HIF-1? expression with magnesium sulfate treatment of PIH. Methods Immunohistochemical streptavidin biotin-peroxidase complex technique (SABC) was used to examine the expression of HIF-1? in 20 cases of PIH and 20 cases of normal placenta. Three groups of PIH were divided according to the degrees of severity. The results were analyzed by computer-assisted imaging and compared by t-test. Results There was significant difference in the expression of HIF-1? between the PIH group and the control group (P

Raf kinase inhibiting protein (RKIP)plays a vital role in various physiological processes and participates in multiple signaling pathways,with a close releationgship with tumor.The mechanism of RKIP down-regulation in neoplasms includes transcriptional regulation,methylation,acetylation,histone modifica-tion,microRNA regulation and NF-κB/Snail/RKIP loop regulation.

Colorectal cancer is one of the most common malignancies with a high risk of liver metastasis in China. Compared with systemic chemotherapy, hepatic arterial infusion (HAI) transports cytotoxic agents directly into the hepatic artery, leading to the persistent level of medicine in tumor cells and the relative lower systemic concentration. With advances in HAI, this technique has been successfully used not only as the pre-and post-operative chemotherapy for the resection of colorectal liver metastases, but also as an ad-juvant chemotherapy after the colorectal radical surgery to prevent the liver metastasis. This review discusses the application and per-spective of HAI in the treatment of colorectal cancer liver metastasis.

Objective:To study the clinical curative effect and nursing interventions of CBP used in critically ill patients. Methods:critically ill patients were enrolled and given CBP treatment, then randomly divided into given nursing intervention and control group were given usual care. Cardiac function, renal function and treatment related complications were observed. Results:after the treatment, E/A, LVEF, LVEDD, Ccr were higher than that before treatment;Scr, BUN levels were lower than that before treatment;cases of arrhythmia, angina pectoris, hypotension, cardiac packing, hypoxemia and puncture point infection, hematoma of observation group were less than control group. Conclusion:CBP therapy can improve heart function and renal function in critically ill patients and the nursing intervention measures can reduce the occurrence of complications in treatment.

To study the anti-cancer activity of the three anti-oncoprotein p185 mAbs established by surface epitope masking method so as to provide some basic information for clinical tumor targeting therapy.Methods: Immnune flurorence staining, MTT assay, soft-ar-gar culture and long-term cell proliferation assay detected the suppressive activities of the mAbs against the breast cancer cells overexpressing p185 and p185-transfected fibroblast cells, and the inducing effects of the mAbs on tumors sensitivity to chemotherapy.Results:The 3 mAbs specifically suppressed tumor cell proliferation and enhanced the sensitivity of tumors to chemotherapeutics. Conclusion:These mAbs have the potentials to develop into the clinical tumor targeting therapeutic reagents of the tumors overexpressing p185.

Objective To access the analgesia effect and side effect of flurbiprofen axetilcombined with sufentanil.Methods Thirty-eight patients underwent cardiac surgery were randomlydivided into two groups with nineteen cases each.Group S was given sufentanil 250μg diluted to 125ml via PCIA after surgery.Group F was given sufentanil 125 gg plus flurbiprofen axetil 150 mgdiluted to 125 ml via PCIA after surgery.The PCIA pump was set at a rate of 0.2 ml/h,bellus dosewas 0.8 ml.lockout time interval was 10 min. Analgesia grade was accessed,vital sign and sideeffects were recorded.Results 'Fhere was no significant difference in analgesia grade between tWOgroups.The side effects were lower in group F than those in group S.Conclusion Flurbiprofen axetilcombined with sufentanil can obtain similar analgesia effects to sufentanil alone,but can reduce sideeffects and fever temperature.

Objective To summarize our experience on laparoscopic appendectomy combined with high ligation of the vaginal process in children.Methods From January 2004 to May 2007,totally 326 patients with appendicitis underwent laparoscopic appendectomy in our hospital.During the operation,by inguinal exploration,83 cases of vaginal process deformity (17 bilateral and 69 unilateral lesions) were confirmed.High ligation of the vaginal process was performed on these patients.Results The operation was successfully done in all of the 83 cases,none of them showed postoperative complications.The cases were followed up for 6 to 12 months,during which only one patient had recurrent inguinal hernia.Three patients developed latent hernia but receined no treatment. Conclusions Laparoscopic appendectomy combined with high ligation of the vaginal process is an safe,effective,and low-cost procedure,leading to quick recovery and less pain for children with appendicitis complicated with vaginal process deformity.

Objective To review the primary experience of video-assisted rigid laser bronchoscopy in the treatment of tracheobronchial tumors. Methods From Sep.2002 to Nov.2004, 13 patients (15 procedures) with tracheobronchial tumors were treated with video-assisted rigid bronchoscope. Benign tumors with small pedicles were removed directly. For benign tumors with wide pedicles or tumors extending beyond the wall of air-way, total enucleating through thoracotomy were employed. In cases with malignant tumors, stenosis or obstructions were relieved by implantation of stents or cautering with electric argoulaser knife. For malignant but resectable primary tumors of trachea and main bronchi, rigid bronchoscopy might serue as a preparation of radical resection. Results Of the 5 patients with benign tumors, 4 received endoscopic total resection and 1 were conversed into thoracotomy. For the 8 malignant cases, 3 received stent implantation, 2 had palliative ablation and 3 got curative resections through thoracotomy. No peri-operative complications or death occurred in this group. Conclusion Total resection of benign tracheobronchial tumors or palliative therapy for tracheobronchial malignant stenosis or preparation of radical resection can be performed safely and efficiently by video-assisted rigid bronchoscopy.
