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 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 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.
