To report one case of postoperative reconstruction of facial squamous cell carcinoma by cervicotho-racic flap and temporal flap in our hospital. Clinical symptoms of the patient are facial mass and tumor ulceration.The patient had chronic bronchitis. On admission, the right side of the patient face was found to have a mass of about 6. 5 cm X 5. 0 cm, and the middle is about 2. 5 cm X 2. 5 cm X 1. 0cm ulcer, the neck has no swollen lymphnodes by palpation. After imaging and pathological examination,the patient was diagnosed as right facial squamouscell carcinoma and chronic bronchitis.

The array CGH technique (Array Comparative Genome Hybridization) has been developed to detect chromosomal copy number changes on a genome-wide and/or high-resolution scale. It is mainly used in human genetics and oncology. Generally PCR amplified bacterial artificial chromosomes (BACs) or cDNAs have been spotted on the arrays as probes. Recently, however, oligonucleotide arrays designed with more flexibility and provide much higher resolution with high sensitivity, have been successfully explored in stead of BAC array CGH and can save considerable time and efforts. There will be a gradual transition from BAC array CGH to oligonucleotide array CGH in the coming years. The combination of oaCGH and other high-through put analysis can lead to discoveries of a host of novel oncogenes, tumor suppressors as well as tumor drug resistance genes. Some major platforms of oaCGH concerning their spatial resolution, optimal probe length, sensitivity, specificity and application in recent years were compared.

Objective To investigate the function of acid pocket in reflux esophagitis. Methods The 15 healthy controls and 24 reflux esophagitis patients were identified by reflux disease questionnaire (RDQ) and gastric endoscopy. The location of subjects' lower esophageal sphincter (LES) was determined by 4 channel esophageal manometry system. Then a single-channel pH electrode was positioned 1 cm below the distal border of the LES to monitor fasting pH for half an hour. After a standard meal, the pH was continuously measured for two hours. Then the electrode was moved to 5 cm above the proximal border of the LES to monitor the dynamic pH for 24 h.Results Acid pocket was found in 16 cases of reflux esophagitis patients(66.67%) and 10 cases of healthy individuals (10/15). Acid pocket occurred earlier in reflux esophagitis group than healthy controls [11.00(4.25-17.00) min vs 30.00(15.50-54.25) min, P<0.05], and the average pH value was lower [1.84(1.59-2. 19) vs 2.32 (1.96-2.71), P<0.05]. There was no statistic difference in mean pH value of gastroesophageal junction and the duration of acid pocket before the meal.Conclusion There is abnormal acid reflux in reflux esophagitis patients, and acid pocket with earlier occurrence and lower pH value may relevant to esophageal mucosal impairment.

Objective To study the endoscopic manifestation of gonorrheal proctocolitis.Methods Retrospectively reviewed and analysed the clinical and endoscopic smaples of 6 gonorrheal proctocolitis cases on the findings of clinical endoscopic features,pathology,mucus smear and cultures.Results Colonoscopic features of rectum and distal sigmoid mucosa revealed varying grades of edema,congestion and abundant mucus in 6 cases;supurative secretion in 3 cases;scattered bleeding spots,local erosive and superficial ulceration in 2 cases. Pathological findings were chronic inflammation in 4 cases,local erosion,necrosis with superficial ulceration in 2 cases.Rectum mucus smear and mucus culture were positive for gonococcus in all 6 cases.Conclusion The colonoscopic and pathological features of proctocolitis merely showed the non-specific changes even in the severe cases.The gram stain and culture of rectal mucus,particularly the later,gave the highest diagnostic significance.

Background Fibrin glue has been utilized to adhere the graft during the pterygium excision with conjunctival autografts.Several relevant clinical randomized controlled trial(RCT) and retrospective studies have been published abroad,but the samples for its effectiveness and safety issue of fibrin glue and suture are still underinvestigation.Objective Current study was to quantificationally assess the efficacy and safety of fibrin glue versus sutures in the application of pterygium excision with conjunctival autografts.Methods Based on established search strategy,a computerized literature search was conducted to identify all citations concerning the RCT for effectiveness and safety evaluation of fibrin glue and suture for the graft fixation during the pterygium excision with conjunctival autografts from MEDLINE ( from 2000 to October,2010 ),EMbase ( from 2000 to October,2010 ),Cochrane Central Register of Controlled Trials ( Issue 4,2010 ),CBMdisc ( 2000 to October 2010 ),CNKI ( 2000 to October 2010 ),and the relevant conference proceedings and references searched by hand was performed as supplement.The included literature was scored with Jadad table.The Cochrane Collaboration' s RevMan 5.0 software was used for the test of heterogeneity or test for overall effect.The effective indexes,such as operative duration,recurrence rate and complication,were evaluated by Meta analysis.Results Six RCTs involving 401 eyes of 377 participants were identified.These literatures were published with English in 2004-2010 from China,New Zealand,Sweden,Israel,Turkey and Malasia and the Jadad scores were 4-5.The quantitatively analysis revealed that fibrin glue appeared to short the operative time compared with suturing method (MD =14.23 ;95% CI:- 16.18- 12.29;P=0.00) and drop the rate of recurrence ( RR =0.49,95% CI:0.26 -0.95 ; P =0.03 ).No significant differences were found in the rate of postoperative graft dehiscence or absence (RR =3.41,95 % CI:0.85-13.68;P =0.08 ).Conclusions Fibrin glue shows the good effectiveness and easy application during the pterygium excision with conjunctival autografts.Long-term follow-up of multi-central RCTs with a larger number of cases are still needed to support this conclusion.
