AIM: To explore the main risk factors related to the incidence of endophthalmitis in patients after cataract surgery in China and to provide evidence for prevention.METHODS: The results of 5 studies on the main risk factors of endophthalmitis in patients after cataract surgery were analyzed by Meta-analysis method.
RESULTS: The pooled odds ratio values and 95% CI of age(≥70), diabetes, vitreous overflow, operative time ( ≥ 10min ), common operating room and control of using time of topical anesthetic were 1. 81(95% CI: 1. 43-1. 69),3. 66 (95% CI: 1. 64 - 8. 16),2. 21 (95% CI: 1. 46 -3. 32),3. 54 (95% CI: 2. 47 - 5. 06),2. 77 (95% CI: 2. 07 -3. 72),2. 09(95% CI: 1. 53-2. 86).
CONCLUSION: The main risk factors of endophthalmitis were the age(≥70), diabetes, vitreous overflow, operative time(≥10min), common operating room and control of using time of topical anesthetic.

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 compare the efficacy of transumbilical-ultrafine gastroscope sympathectomy for severe palmar hyperhidrosis using two distinct levels of T3 and T4.Methods A total of 84 cases with severe primary hyperhidrosis were randomly allocated to undergo either T3 sympathectomy treatment (T3 group, n =42) or T4 sympathectomy treatment (T4 group, n =42) with no difference between the two groups.The operation time, postoperative hospital stay, patient's hands hyperhidrosis, axillary hyperhidrosis,complications were recorded at follow-up in 1,3,6,12 months.Results Operation on 84 patients were successful with mean operative time of T3 group being 55.02 ± 10.61 min and T4 group being 55.36 ± 10.51 min(P > 0.05).The mean postoperative hospital stay were both 1.5 days.Patients were followed up for diaphragmatic hernia, umbilical hernia, Horner's syndrome and other serious complications for 12 months.No postoperative recurrence of palmar hyperhidrosis, severe compensatory sweating occurred in either group.The number of improved patients in T3 group's palmar hyperhidrosis,axillary hyperhidrosis, and foot hyperhidrosis were :42/42 cases, 10/16 cases, 21/29 cases, while those in T4 group were: 42/42 cases,16/17 cases 18/28 cases.Axillary hyperhidrosis improved to a larger extent in T4 group than in T3 group (P <0.05).There were 16(15 mild and 1 moderate)compensatory sweating in T3 group and 7(6 mild and 1 moderate) compensatory sweating in T4 group (P < 0.05).Conclusion T3 and T4 thoracic sympathectomy using transumbilical-ultrafine gastroscope for primary palmar hyperhidrosis are safe, effective, and feasible.T4 sympathectomy is more effective in improving axillary hyperhidrosis than T3 and shows lower occurrence of postoperative compensatory hyperhidrosis.

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.
