AIM: To observe the interocular symmetry of primary angle-closure suspects` (PACS) parameters using IOL Master.METHODS: A cross-sectional observational study.Totally 112 eyes from 56 subjects were enrolled to detect the difference of the bilateral axial length (AL), anterior chamber depth (ACD) and white to white distance(WTW), and to evaluate the correlation between the interocular differences of △AL, △ACD and △WTW and age, gender.RESULTS: All the parameters were analyzed by paired-samples t test and there were no significant interocular difference (P>0.05).There was no relation of ΔAL,ΔACD and ΔWTW with age and gender.CONCLUSION: Interocular symmetry of parameters by IOL Master was observed in PACS, and we found that the symmetry would not be altered when the age and gender had changed.

OBJECTIVE: To study the clinical efficacy of mouse nerve growth factor (NGF) in the treatment of sudden deafness. METHOD: A retrospective analysis was performed on 115 cases of hospitalized patients who were suffered from sudden deafness. Patients were divided into two groups according to treatment medicine. Control group: patients were treated with intravenous vasodilators, energy mixture, steroid pulse therapy, and methylcobalamin neurotrophic therapy. NGF group: intramuscular NGF treatment was added on the basis of conventional therapy mentioned above. Both treatments lasted 14 days, the total efficiency were compared. Patients were further divided into sub-groups according to age, duration and the level of pre-treatment PTA, and the treatment efficiency was further compared. By SPSS 11.0 statistical analysis, a P < 0.05 was considered as statistical significant difference. RESULT: (1) The total efficiency of NGF group was significantly higher than control group. (2) Regard of age, the efficiency of NGF treatment group was significantly higher than control group. (3) For the patients whose duration were less than 7 d, or the PTA < or = 60 dBHL, the efficiency of NGF group were significantly higher. For the patients whose duration were more than 7 d, or the PTA>60 dBHL, the efficiency of NGF therapy was not superior to the traditional treatment. CONCLUSION NGF can significantly improve the symptom of patients with short duration or low PTA. For this kind of patients, NGF adjuvant therapy should be recommended. For the patients with longer duration and higher level of PTA, NGF therapy is not advocated. NGF treatment should not be in consideration of the age.

Objective To compare the surgical outcomes between laparoscopic and open surgeries in treatment of ectopic oviduct pregnancy, and investigate the clinical value of laparoscopic surgery. Methods Two hundred and forty-six patients with ectopic oviduct pregnancy in our hospital from June 2009 to March 2013 were retrospectively analyzed. 134 cases were treated with laparoscopic operation and 112 with open surgery. Some parameters such as operative time, blood loss, usage of pain-killer, hospital stay were compared between both groups. Results All operations were successful. Laparoscopic surgery was shown to be superior to open operation in the parameters of operative time, blood loss, usage of pain-killer and hospital stay ( < 0.05) . Conclusion Compared with open operation, laparoscopic surgery has the advantages of less trauma and rapid postoperative rehabilitation. It may become the first line treatment for ectopic oviduct pregnancy.

Carotid ultrasound examination is a very mature examination method, it is widely used in clinical diagnosis and health checkup. Carotid ultrasound examination plays an important role in the prediction of the occurrence of cardiovascular disease. However, there are still certain problems in the application of the examination in the domestic health checkup population, which mainly include that the method and the standard are not unified, and the reporting form is not standardized. Carotid ultrasound examination must be standardized as soon as possible.

Objective: To identify the influence of extracts and active components of Rhizoma Coptidis on gastric smooth muscle contractility of guinea pigs, and to explore the potential pharmacological mechanism of Rhizoma Coptidis in "invigorating the stomach" and "impairing the stomach". Methods: Observing the effects of the water extract and the alkaloids from Rhizoma Coptidis (at doses ranging from 0.3 to 1 000 mug/L) and other active components such as berberine, palmatine and jatrorrhizine (at doses ranging from 0.3 to 1 000 mumol/L) on the spontaneous and electrical field stimulation (EFS)-induced contractions of antral circular smooth muscle strips from guinea pig stomach via a force transducer in vitro. Results: The water extract or the alkaloids from Rhizoma Coptidis could improve the spontaneous contraction at the low doses, but inhibit the spontaneous contraction at the high doses. Berberine, palmatine and jatrorrhizine also showed the similar effects. Moreover, the water extract and the alkaloids of Rhizoma Coptidis, as well as berberine, palmatine and jatrorrhizine could increase the EFS-induced contraction. Among the three monomers, jatrorrhizine exhibited the most potent effect on EFS-induced contraction. Conclusion: The effects of Rhizoma Coptidis in "invigorating the stomach" or "impairing the stomach" may be related to its effect on gastric smooth muscle contractility. Berberine, palmatine and jatrorrhizine are all effective components of Rhizoma Coptidis affecting the contraction of gastric smooth muscle, among which jatrorrhizine is the most potent agent in promoting the contraction while berberine is the most potent one for inhibiting the contraction.

Objective To investigate the pathological diagnosis of high-grade intraepithelial neoplasia in gastric biopsy.MethodsOne hundred and forty-three cases diagnosed by gastric biopsy as high-grade intraepithelial neoplasia were analyzed by light microscopy,and were compared with the pathological findings of surgical specimens in 60 cases and a second biopsy in 13 cases.Results Among the sixty cases treated surgically following the gastric biopsies,no carcinoma was found in 6,while the other 54 were diagnosed as gastric adenocarcinoma,27 in advanced stage and 27 in early stage,respectively.Fifteen cases were well-differentiated,24 moderately-differentiated,12 poorly-differentiated and 3 were of mucinous type.Four of the 13 cases with a second biopsy were diagnosed as well-differentiated adenocarcinoma,8 low-grade intraepithelial neoplasia and 1 chronic inflammation.The colorectal adenomas-like changes were morphologically found in 6 surgically-treated cases without carcinoma,5 of whom mucous muscles were not found by biopsy.Fibroblastic reactions were found in 9 cases,all of which were diagnosed as adenocarcinoma in surgical specimens.Conclusion Ninety percent of the cases who are diagnosed as high-grade intraepithelial neoplasia by biopsy may have already been complicated with adenocarcinoma.The location and depth of the specimen in gastric biopsy have a considerable influence on pathological diagnosis.The fibroblastic reaction may be considered as an important marker for gastric adenocarcinoma in pathological diagnosis of gastric biopsy.
