Objective:To evaluate the clinical efficacy of treatment of sudden deafness using hyperbaric oxygenation, and to provide guidance for its treatment. Methods:The studies about sudden deafness treated with hyperbaric oxygenation combined with drug were retrieved in Cochrane Library, PubMed , MEDLINE, Wanfang Database and CNKI up to July 2016.RavMan 5.3 provided by Cochrane was used for Meta-analysis.Results:Thirty-nine studies which were randomized controlled trials (RCTs)were included, a total of 4 599 cases,of which 2 418 cases received hyperbaric oxygenation therapy combined with drug treatment as treatment group and 2 181 cases received drug treatment alone as control group.A total of 36 studies about the comparison of clinical efficacy between treatment group and control group were included in the Meta-analysis, the result showed that treatment group had a significant clinical efficacy than control group(RR:1.26,95%CI:1.22-1.30,P<0.0001).A total of 6 studies about the improvement of the pure tone average(PTA)in the two groups were included in the Meta-analysis, the PTA gain was significant better in hyperbaric oxygenation group(WMD:11.8,95%CI:4.77-18.83,P<0.000 1).A total of 11 studies about the stage of using hyperbaric oxygenation therapy were included in the Meta-analysis, the result suggested that the early use of hyperbaric oxygenation therapy had better effect than the late use of hyperbaric oxygenation (RR:1.42,95%CI:1.31-1.53,P<0.000 01).Conclusion:The clinical efficacy of hyperbaric oxygenation combined with drug therapy is better than drug therapy alone, the PTA gain is significantly improved and the introduction of hyperbaric oxygenation therapy at the earlier stage shows better results.

Robotic system helps surgeons in performing surgery. Currently Da Vinci system is the most popular. Da Vinci system has been used for the stomach and bowel diseases in 27 cases(18 cases of stomach and 9 cases of colon and rectum) in the Zhongshan Hospital, Fudan University. Accurate preoperative staging is crucial, and Da Vinci system is advantageous in lymph node dissection, preservation of nerve plexus, and complete resection of mesorectum. Adoption of gastrointestinal tract reconstruction technique should depend on the operation and experience in surgery. Though Da Vinci system has limitations and the cost is high, it is believed to be the future trend.

Objective To investigate the effects of different therapeutic strategies on recurrence of postoperative Crohn's disease (CD) patients.Methods From September 2009 to September 2014,85 CD patients with intestinal resection were enrolled.The clinical features and maintenance therapeutic medication were retrospectively analyzed.The patients were divided into non-treatment group (induding continuously or cumulatively taking medicine less than three months),5-aminosalicylic acid (5-ASA) group and immunosuppressant agents group (including azathioprine,methotrexate and thalidomide).Kaplan-Meier method was performed to compare the recurrence rate in postoperative CD with different therapeutic medication and the risk factors of postoperative recurrence were also analyzed.Results Among 85 CD patients,there were 32,21 and 32 patients in non-treatment group,5-ASA group and immunosuppressive agents group,respectively.After surgery,the one year accumulated clinical recurrence rate of immunosuppressant agents group was 12.5％ (4/32),which was significantly lower than that of non-treatment group (56.3％,18/32) and 5-ASA group (38.1％,8/21),and the differences were statistically significant (x2 =12.250,P＜0.01;x2 =4.102,P =0.043).After surgery,the two years accumulated clinical recurrence rate of immunosuppressant agents group was 12.9 ％ (4/31),which was significantly lower than that of non-treatment group (75.9％,22/29) and 5-ASA group (47.6％,10/21),and the differences were statisitcally significant (x2 =17.840,P＜0.01;x2 =6.597,P=0.010).After operation,the one year accumulated endoscopic recurrences rates of non-treatment group,5-ASA group and immunosuppressant agents group were 39.1％ (9/23),5/16 and 34.6％ (9/26),respectively;while the two year accumulated endoscopic recurrence rates were 59.1％ (13/22),6/16 and 44.0％ (11/25),respectively.However,there was no statistically significant difference among the groups (all P＞0.05).Penetrating lesion was an risk factor of postoperative clinical recurrence in CD patients (x2 =4.963,P=0.026,oddsratio (OR) =2.221,95 ％ confidence interval (CI) 1.121 to 5.775).Conclusions Immunosuppressive agents rather than 5-ASA have remarkable effects in preventing postoperative clinical recurrence in CD patients.Postoperative clinical recurrence is more likely to happen in patients with penetrating lesions.

Objective To analyse the clinical effect of Quantianma capsules combined with flupentixol and melitracen tablets on chronic migraine. Methods 130 patients with chronic migraine were treated with flupentixol and melitracen tablets, were divided into control group and observation group, 65 patients in each group. The observation group were given to Quantianma capsules. Results The effective rate of observation group with 90.77% was higher than control group with 73.85%(P<0.05). After treatment, the number of migraine attacks, duration time, VAS score, HAMA and HAMD score and mean flow velocity of cerebral artery of two groups were lower than pre-treatment and observation group were lower than that of control group(P<0.05). Adverse reactions were similar in the two groups. Conclusion Quantianma capsules can improve the efficacy of treatment of chronic migraine combined with flupentixol and melitracen tablets and improve condition with few adverse effects.

Objective To explore the value of dexamethasone(DEX) for neuronal cell injury and death by observing the effect of DEX on excitatory amino acid(EAA) and monoamine neurotransmitter in cerebral tissue of neonatal rat with hypoxia-ischemia.Methods Hypoxic-ischemic neonatal rat models were established,the levels of EAA and monoamine neurotransmitter in cerebral tissue were analyzed by using capillary electrophoresis and fluorospectrophotometry method.The rats were divided into 4 groups: small dose DEX group pre-treated with DEX(0.5 mg/kg) prior to hypoxia-ischemia,large dose DEX group pre-treated with DEX(10 mg/kg) prior to hypoxia-ischemia,HIE group and shamful operation group.Results The levels of EAA and monoamine neurotransmitter contents in HIE group were significantly higher than those in shamful operation group(P0.05).EAA contents of large dose DEX group greatly decreased compared with HIE group (P

ObjectiveTo discuss the role of transient receptor potential vanilloid 1 (TRPV 1) in the regulation effect of electroacupuncture on gastric motility.MethodTRPV1 gene knock-out mice (KO mice) and wild-type C57BL/6 mice (WT mice) were selected to receive acupuncture at Zusanli (ST36),Quchi (LI11), Zhongwan (CV12), and Weishu (BL21), and the intragastric pressure was observed before and after acupuncture.ResultElectroacupuncture at Zusanli caused both excitation and inhibition in WT mice, predominated by mild excitation, while electroacupuncture at Weishu, Quchi and Zhongwan all caused inhibition effect; in the KO mice, electroacupuncture at Zusanli, Quchi, Zhongwan, and Weishu all inhibited gastric motility.Conclusion TRPV1 bears certain regulating effect on gastric motility, andacupuncture can inhibit the gastric motility in TRPV gene KO mice.

Objective To report the therapeutic results of Hybrid external fixator in treatment of open metaphyseal fractures of the tibia.Methods From March 2000 to July 2004,19 cases of proximal tibial meta- physeal fractures and six cases of Pilon fractures were treated with Hybrid external fixators.By Gustilo classification, eight cases were of typeⅡ,10 typeⅢA,five typeⅢB and two typeⅢC.The wounds were closed directly after thorough debridement in 21 cases,and closed by pedicled flap transposition or free flap transplantation in four. Fasciotomy was performed in three.Closed indirect reduction of the fractures was done in 11 cases,while open reduction was carried out through an extended wound or a limited incision in 14.Anatomical reduction was done for the articular fractures,if any,and Hybrid external fixators were employed to stabilize fractures in all the cases in this series.Results All the patients had a mean follow-up of 15.7 months (ranging from 9 to 26 months) which re- vealed bone union of the fracture in all cases with a mean healing time of 8.8 months.Two patients had their external fixators replaced with plates and iliac bone graft to get fracture union.The fixators were removed 2.9 to 21 months (mean,9.4 months) after operation.Except for two cases of secondary healing,all the wounds healed primarily without serious complication,such as infection.The final follow-up revealed a knee motion range of more than 90?in 15 cases,less than 70?in four,whose knee motion range was improved to more than 90?after knee release performed one year later.In all the six cases of Pilon fractures,the ankle joint recovered normal range of motion.Traumatic arthritis occurred in two cases of Piion fracture 11 months after operation.Evaluation by Rasmussen's functional and radiological scoring system demonstrated excellent knee function in 13 cases,good in three,fair in two and poor in one,with a good to excellent rate of 84.2%.The ankle function was excellent in three cases,good in two and poor in one,with a good to excellent rate of 83.3%.Conclusions In treatment of open tibial metaphyseal fractures, the Hybrid external fixator can well maintain the stability of the fragments with a low incidence of soft tissue com- plications and insignificant interference with the knee motion.However the bone healing time can be prolonged with a definite rate of nonunion.
