Cancer Research and Clinic 2007;19(z1):57-59
Objective To study the level of serum vascular endothelial growth factor(sVEGF)in advanced non-small cell lung cancer(NSCLC) and its clinical significance.Methods Serum level of VEGF was detected by ELISA method in 96 patients with advanced NSCLC.sVEGF level was analyzed after giving 2-4 cycles of cisplatin-based chemotherapy.At the same time,serum level of VEGF in 50 healthy controls was detected.Results The level of sVEGF was significantly higher in patient with lung cancer than in control group (P<0.01).No statistical significant defference was observed between sVEGF level of stage Ⅲ and Ⅳ NSCLC patients,the patients with squamocellular lung cancer and adenocarcinoma(P>0.05);Descended sVEGF level was found in the patients with response to chemotherapy(P<0.05).Conclusion sVEGF can be used to evaluate chemotherapy response and diagnoses in the patients with advanced NSCLC.

Objective To investigate the effects of parecoxib pretreatment on the intrapulmonary shunt during one-lung ventilation in patients undergoing esophageal cancer resection.Methods Forty ASA Ⅰ or Ⅱ patients of both sexes,aged 25-64 yr,weighing 45-70 kg,with body height 156-178 cm,undergoing elective esophageal surgery,were randomly divided into 2 groups (n =20 each):normal saline group (group NS) and parecoxib group (group P).Parecoxib 40 mg (in normal saline 10 ml) was injected intravenously 30 min before anesthesia in group P,while the equal volume of normal saline was given instead of parecoxib in group NS.Anesthesia was induced with iv injection of propofol,fentanyl and rocuronium.Bronchial blocker was inserted after tracheal intubation and the correct position was confirmed by bronchoscopy.Anesthesia was maintained with iv infusion of propofol and remifentanil and intermittent iv boluses of atracurium.HR,MAP,SpO2 and mean airway pressure (Pmean)were determined at 5 min of two-lung ventilation,at 40 min of one-lung ventilation,and at 30 min after re-expansion of the collapsed lung (T0-2).Blood samples were taken simultaneously from jugular vein and radial artery for blood gas analysis.Intrapulmonary shunt (Qs/Qt) was calculated.Results There were no significant differences in hemodynamic parameters and Pmean between the two groups (P > 0.05).PaO2 was significantly lower,while Qs/Qt was significantly higher at T1,2 than at T0 in groups NS and P (P < 0.05).PaO2 was significantly higher,while Qs/Qt was significantly lower at T2 than at T1 in groups NS and P (P < 0.05).Qs/Qt was significantly lower at T1,2 and PaO2 was significantly higher at T2 in group P than in group NS (P < 0.05).Conclusion Parecoxib 40 mg injected intravenously at 30 min before anesthesia can reduce the intrapulmonary shunt during one lung ventilation in patients undergoing esophageal cancer resection.

Endophytic fungi which reside in the tissue of mangrove plants seem to play an important role in the discovery of new biologically active substances. During the course of screening for the antimicrobial metabolites from the endophytic fugus Penicillium sp. FJ-1 of mangrove plant Avicennia marina, a new aurone glycoside (1) was isolated by repeated column chromatography on silica gel and recrystallization methods. The structure of 1 was elucidated as (Z)-7,4'-dimethoxy-6-hydroxy-aurone-4-O-β-glucopyranoside, on the basis of spectroscopic analysis. Compound 1 exhibited antifungal activity against Candida sp., with the potency comparable to amphotericin B and much better than fluconazole. Compound 1 can also inhibit extracellular phospholipase secretion in a concentration-dependent manner.

Objective To observe MSCT and clinical features in patients of laryngocarcinoma combined with other primary carcinomas. Methods Five patients of laryngeal cancer combined with multiple primary cancer were enrolled in the study. Three paitents had long-term smoking history more than 20 years. Three paitents had various degree of radiotherapy, chemotherapy and immunotherapy. The second primary cancer located in right upper lung lobe in 2 patients of synchronous cancer and 1 patient of metachronous cancer. The others located in soft palate, uvula and the left side of zone Ⅱ and zone Ⅳ in the neck, respectively. MSCT and clinical characteristics were analyzed. Results Five patients of multiple primary cancers included 2 patients of synchronous cancer and three patients of metachronous cancer. MSCT found the appearances of malignant tumors in various parts in all 5 patients and cervical lymph nodes metastasis in 2 patients. Conclusion The possibility of prime laryngocarcinoma combined with other primary cancers should be considered when other organ malignant tumor was detected in patients with laryngeal carcinoma, especially in patients with history of long-term smoking, radiotherapy and chemotherapy and immunotherapy. Long-term following-up of cervix and other organs should be taken for the postoperative patients of laryngocarcinoma.

Objective To observe the clinical characteristics and surgical methods of strabismus following external approach for retinal detachment,and explore the common factors related to deviation angles of strabismus.Methods Twenty-five cases of secondary strabismus following external approach for retinal detachment underwent strabismus surgery were recruited,and the follow-up time was from 5 months to 41 months.Ophthalmic examinations were performed before operation.Clinical characteristics of these cases were observed by intraoperative exploration,including preoperative and postoperative eye position and ocular movement (at 1 week and further followup).The preoperative and postoperative deviation angles of strabismus were evaluated according to the times of retinal detachment operation,postoperative BCVA and the surgery procedure of hang-back recession.Results Before strabismus operation,all cases underwent abnormal eye-movements,8 cases suffered from diplopia,and scar adhesions were observed in all involved ocular muscles during operation.Seven cases underwent weakening procedure of extraocular muscle,18 cases underwent weakening procedure plus strengthening procedure.Ten cases underwent hang-back recession among them.At 1 week and the final follow-up,the eyeball in21 cases and 15 cases were in position,4 cases and 9 cases were in undercorrection,5 cases and 7 cases were in limitation,and 2 cases and 1 case were in diplopia.The more operations were performed in retinal detachment,the more scar adhesions were presented,and statistical significance existed with the mean deviation angles before and after operation(in a week) between cases that had one-time and over-one-time of retinal detachment surgery (P =0.01,0.00).No difference of mean deviation angles was found at one week after operation and at follow-ups between the cases with and without hang-back recession (P =0.26,0.63).Conclusion Abnormal eyemovements,diplopia and scar adhesion are the most common clinical characteristics of strabismus following retinal detachment surgery.Times of retinal detachment operation and postoperative BCVA can influence the deviation angles of strabismus,and hang-back recession seems the safe and effective method of strabismus surgery.

Objective To explore the inhibitory action of antisense c-jun oligodeoxynucleotides(ODN) on matrix metalloproteinase(MMP) expression of fibroblasts induced by ultraviolet B (UVB). Methods The c-jun and c-fos protein expression induced by UVB were measured by Western blot. The mRNA expression of c-jun was determined by reverse transcriptase polymerase chain reaction (RT-PCR) after transfection with c-jun antisense ODN. The pro-MMP-1 and MMP-3 synthesis of fibroblasts was measured by ELISA after treatment with UVB and antisense c-jun ODN. Results The UVB-induced c-jun protein expression of fibroblasts increased to 1.8, 2.6, 3.3 times compared with that of non-irradiated controls,while there was no significant change in c-fos protein expression. The pro-MMP-1 and MMP-3 synthesis induced by UVB irradiation increased obviously. After transfection with different concentrations of c-jun antisense ODN, the UVB-induced c-jun mRNA expression could be significantly inhibited(P

0.25)levels in the two groups.In the group treated with42mJ/cm 2 UVB irradiation followed by the addition of EGCG,the numbers of apoptotic and dead cells and Fas mRNA were decreased,but bcl-2protein was increased.Conclusions Low dosage of UVB irradiation could induce apoptosis of keratinocytes.High dosage of UVB irradiation might result in cell death.EGCG could reduce UVB-induced apoptosis of keratinocytes by increasing bcl-2protein and decreasing Fas mRNA.
